Ooo. Me Grandpa was a custodian and a very smart man. Watch your mouth. I work for a school and the janitors here are smart folks too. Most of all, they treat the lowly tech guy with respect in spite of his job and the fact that he lives in his parents basement and has never touched a girl (not a real girl anyway).
they started it in '63, they didn't finish it till '64. rtfa
Then VB came, and a language was created that was muscular enough to script Word macro viruses, but simple enough to enfuriate good programmers (I mean, really, no short circuit boolean operators? It makes me weep.)

Ok, who remembers the Star Trek game from Dartmouth? You know, the one where you got to enter coordinates to move the ship to, then fire photons and phasers at Klingons? You could even consult the library computer! Failing that, who remembers coding the "trench" game?

What it really means is that the programmers won't program exactly the way Dij wants them to do. It is not "good" or "bad": just different. Programming should not be a straitjacket: the more options and the more different ways to do thing, the better. Those who think that there is no place for anything like a GOTO should look at html.
Don't blame Durga. I voted for Centauri.
Microsoft certainly doesn't claim that.
Nor do they claim that
They do claim that, because it's true.
BASIC was always the applications and scripting language at Microsoft. For a long time, DOS and the early Windows shipped with a free basic interpreter (sadly, those days are over).
Visual Basic remains one of Microsoft's flagship products. It's philosophy is similar to the original BASIC philosophy: you shouldn't have to be a comp sci graduate to write computer programs. Whether VB succeeds in that regard is another question, but it's what they intended.
BASIC is still Microsoft's language for application automation (think Visual Basic for Applications), Web development (ASP with VBScript), and as a tool control language for gluing together objects written in lower level languages. In a sense, some form of BASIC fills the roles in Windows that Scheme, Perl, and TCL occupy in UNIX.
All's true that is mistrusted
That is because array indexes start at 1 instead of zero. So it's really 41 years if you start from year one.

This brings me back... the first language I ever learned to code in was C++... but before that, I had learned Qbasic. ;)
...but I think, the biggest fad was making console style RPGs. I'd like to think that I had a small hand in starting that fad, with a little Qbasic RPG demo I released in 1997. Some of you may have played it, it was called "Lianne in... the Dark Crown". Yes, fun times... fun times indeed.
I think it was the limited nature of the language which kept me interested in it for so long. Those DOS memory limits were fun... coding a 2D RPG, and trying to stay within around 450KB, so it would run on most people's DOS machines. It was a challenge, I tell you... and trying to keep the code neat, and tidy... also a fun challenge.
To this day, I'm still amazed at some of the things which people were able to do with QBasic, and QuickBasic... fast raycasters, 3d polygon game engines, even voxel engines!
I think, I'll go looking for all those old Qbasic games. They may not have been much, but they were fun to play.
Well I'm glad BASIC exists because I probably would not have started programming without it. Can you imagine trying to learn C or something like that when you are 13 (circa 1984) and have no other programmer friends and no internet or BBS to get sample code from. Also C and Pascal compilers cost big money back then. Borland's Turbo Pascal was probably the other big hobby language back the as well. It probably damaged my skills, but I think I have overcome most of the damage.
And Windows 3.1 never would have been as accepted as it was if not for VB 1.0. I think VB was probably the thing that got a lot of people on Windows because programming Windows in C at that point was very complicated for the home hobbiest.

Hey, stop using janitors as some lowest-common-denominator! Rather "The language was so simple even programmers could use it."

Ah yes, BASIC. I remember it distinctly as it's what I used for the longest time. Didn't have to declare your variables, had to contend with line numbers (that renum thing came in very handy), and of course the ever-popular GOTO statements.
;-)
Eventually I evolved onto qbasic with its functions and subs and (gasp) no line numbers! Then there's VB and VBA. The most fun I've had with those are the shell calls.
On machines that are so locked down that you can't even traverse directories let alone get a shell prompt, you run your form of BASIC, and do basic shells through it or even shell to cmd.exe or command.com -- at one point, I had a really lamed out, simple, featureless, just for fun version of netcat that executed shell commands, piped it to a text file, and had the text file's contents sent through the network. (this with VB's socket stuff). If nothing else, it was a good way to make fake Novell login prompts in the mid 90's.
In the end, not a lot of people will be taken seriously for knowing BASIC, but since it was the first language I used, I appreciated the retro code.

Dammit... Missed out a line. Now I remember why I should always increment line numbers by 10.
Today's VB and similar derivatives bears so little resemblance to Dartmouth BASIC that it's hardly the same language. If it wasn't for FOR/NEXT and DIM, you might not recognize it at all.
But the old line-oriented BASIC had some advantages in the bad, old days:
1) Interactive editing is difficult to do on a teletype -- many schools only had a hardcopy terminal to a timeshare service. Being able to drop a line in the middle, or retype a single statement really really helped learn what was going on, without having to re-send the entire program. Even with a primitive CRT, full-screen text editors were of poor quality -- dropping in statements helped to debug and fix features.
2) Later, it was ubiquitous: You could write the same abusive repeating naughty-word program at a Radio Shack, an Apple Dealer, or a department store selling Commodore PETs.
3) It beat COBOL or FORTRAN. The only thing with BASICs interactivity might be FORTH -- imagine if we'd been saddled with page-delimited, stack-based code in all our micros. It's a lot harder to learn, but would have helped modularity and library development.
Design for Use, not Construction!
I must admit that I share his lament. The programmer-to-user ratio got considerably worse as the ubiquity of computers increased.
When I got my first computer (comment hoping skip the 'geek pissing match'), the majority of other people with computers were using them to write programs. As the PCs (now workstations) got adopted (then coopted) by 'business' for them to do their thing, the computer became a 'tool'. I never stopped programming, but all my non-geek friends started to get in on the computer-owning game. Most of them couldn't write a line of BASIC with a gun to their head, even though they have the capacity to do so, but gosh, they all thought they were just whizz-bang computer users! *sigh*

That's a very obvious statement. You basically said that a bad program written in one language could have been written better in the other language. But any program written badly in any language is going to be better when written better, regardless of language.
The comparison I believe the original post was making was between a good VB app and a good C app and between those, I'm guessing the C one would be better.

VBScript is surprisingly capable. Read more about it here.
Don't believe it, kids. If your brain hasn't been ruined by age 7, you can unlearn any bad habits you pick up. His remark is of a stupidity level equal to "if you learn French at school, you won't be able to learn German."
As a matter of fact, not only did I once inherit a program that someone had written - well - on a BBC micro that was a pleasure to maintain, I once myself had to write a quick and dirty assembler for an obscure microprocessor in HP Basic, having no other resources available in a crisis. Despite which I have never once had the urge to use labels in C.
Panurge has posted for the last time. Thanks for the positive moderations.
Don't forget to PEEK before you POKE!
Computers died for me the day the stopped shipping them with built-in BASIC.
Seriously, though. The computers of the 80's were great for learning programming on. Not that BASIC is a good teaching language, but it was accessible and simple.
Modern computers have too many features that you want serious programmers to have access to (complicating languages), and modern languages have all sorts of safety, structure, and OO features that are great for serious programmers but also complicate things for beginners.
Breaking into programming is much harder than it used to be.
At first I was considering having my sig in BASIC:
10 PRINT "Jorkapp is a Programmer"
20 GOTO 10
but it was too - Basic. IMO, my sig in C is more 1337.
Frink: Nice try floyd, but you were designed for scrubbing, and scrubbing is what you shall do.
I was introduced to BASIC first on a friend's Apple IIe and subsequently on my own first computer, an original Macintosh.
First programs included the standard:
10 print "Enter your name: "
20 input NAME$
30 print NAME$ " is a doofus."
40 goto 30
About that time, I started getting 3-2-1 Contact Magazine, a science and nature periodical written for kids who had grown out of Sesame Street and The Electric Company. In the back of every issue was the "BASIC Training" feature, which had simple games and programs for a variety of platforms. The IBM versions were usually the only ones I could use; Apple IIe and Commodore 64 PEEK and POKE calls were meaningless in Mac MS-BASIC.
But later, BASIC facilitated an (extremely sketchy) introduction to the Macintosh toolbox. MS-BASIC on the mac had built-in pseudo toolbox calls so that you could change fonts, draw graphics primitives and buttons. I ended up writing a grade tracking program that was a snare of interwoven GOTOs and GOSUBs.
I breezed through two years of programming courses in high school and learned C in my own time. Looking back, I'm a little ticked off that my HS didn't offer "real" computer science with Pascal or C or any sort of AP treatment.
Then I learned Perl. Now I do websites. I've forgotten most of BASIC. I have been told this is a good thing. But sometimes (actually, lately, more and more) I have to deal with VBScript and I see "LEFT" and "MID" and I think "what the hell is this crap?"
Ah, memories.
A real programmer can extract useful work from anything from a pile of matchboxes to a state of the art cluster without bitching.
Doesn't it make you feel good to know that our freedoms are protected by politicans, lawyers and journalists.
You don't maintain your own programs then, do you?
;)
I've had to maintain programs written by developers who, like you apparently, separated out the maintainability aspects from their concept of "well-written" code.
Well written code does not mean written fast - it means the next guy down the line, after you've moved on and forgotten about it, can easily follow the logic and make changes with minimal effort. GOTO's almost never facilitate this. Please trust your peers on this - it's been debated often enough and long enough by those in the know that it's no longer a subject for reasonable debate. In fact, defending the use of GOTO usually shows one of two things:
1) Inexperience -or-
2) Old Age (meaning the behaviour is so ingrained one simply can't comprehend anything different).
Of course, I'm assuming you have the option to not use GOTO. If the language you use has no control structors other than Jumps and Labels, then obviously you have no choice. But I would argue that even if that's the case, you're probably using an old language for one of two reasons:
1) Not experienced with anything else -or-
2) Too old and stubborn to move on to anything else (meaning the behviour is so ingrained that you probably sit alone in the corner pumping out Cobol not even aware that you were laid off months ago and replaced by the Janitor who took a crash course in Javascript).
Nothing stopping you from using structure in BASIC but your own mind.
Free Mac Mini Yeah, it's

1. When I and many other people started out with computers, BASIC was the only game in town. Yes, there was assembler and other languages, but its easy to forget these days that information was hard to come by pre-web and indeed, for children who don't have the disposable income for specialist magazine subscriptions. Libraries typically had a couple of computer books, but these would be non-specific description books (that no longer exist as genre really) explaining that a computer had ROM, RAM and you could hook it up to a printer and a VDU! etc. etc. They had hand-drawn "screenshots" of space invaders and pac-man. BASIC was easy enough that we could get started without being put off. On Slashdot its easy to be intellectually macho, but theres a lot to be said for a low learning curve that encouraged you ever onward.
2. BASIC today. Well, its probably not for serious programmers. However, what is often forgotten here is that not everyone who programs is a professional programmer. Or wants to be. For very simple programs, GOTO is no sin. At least when the alternative is no program at all and, say, organising data in a text file by hand or "manually" in Excel or something. Bad habits are not a problem here, because one is never going to go on to have to write mission critical software in C or whatever. I know there are modern scripting languages that are perhaps just as easy to use, but you might be surprised how many people you might have thought have difficulty programming a VCR will break out QBASIC or VB when they need 20 line quicky knocking together and the programmers are "busy until further notice". Its easy to belittle this from a position of knowledge and authority, but relatively speaking these people are your friends in a landscape of PHBs that think programs just happen.
So in conclusion, BASIC is often better than nothing. That might sound like feint praise, but like I say, for the non-specialist that can be quite a valuable thing. Computer programming for the masses. Mock it at your peril.

GOTO's make spaghetti code. It is very hard to trace through, especially if the code is uncommented.
Ever tried to sift through someone's OOP program that is poorly documented and methods are badly named? It's just as bad. Ever seen a method that calls six others methods in different objects in it's body which are all overloaded 5 or 6 times? Bad/Sloppy programming spans all languages and isn't confined to a goto statement.
How about poorly named method signatures? For example
String getNumber(String x, int i, boolean q, vector a)
I've seen crap like this before from programmers.
Try maintaining code full of goto's. Good luck.
No it's not the best thing in the world to do, but if it's well documented it's not as bad as you make it out to be. I started out in basic when I was 7, and I work now as a Java programmer. I would gladly take well commented code with GOTO's over poorly done OOP code.

Proverbs 21:19
I was one of four students in a pilot program in 4th grade (1980) wherein we learned BASIC programming (Apple II) and "New Math" (don't even get me started.)
After learning the basics, I started my first project - a random text generator. I wanted to see if, left to its own devices, the Apple II would eventually reproduce the works of Shakespeare. Or at least, produce a few dirty words on its own.
I spent two days coding (never having used a keyboard before, typing was arduous)
The program went like this:
10 A=INT(RND(1)*30) +1
20 REM
30 IF A=1 THEN $B="A"
40 IF A=2 THEN $B="B"
...
340 IF A=30 THEN $B="."
350 PRINT $B;
360 GOTO 10
If I recall, there was no "copy" or "paste" function in the boot ROM AppleII BASIC. Typing this was hell on my 9-year-old fingers.
The good news is, the program worked. The bad news is, after I'd finished it, the teacher showed me how to cut 29 lines out of my program using the $CHR() function. I wanted to shoot him.
All in all, BASIC served me well. It's a great intro programming language for pre-teens.

The program's source is the haiku, not its output.
That is its biggest strength.
:-) Once you introduce a kid to the concepts of do loops, for loops and if..then statements, it is so much easier to learn a complicated language like C. It's a pity you don't have QBASIC shipping with Windows machines any more. Vbscripting is not at the same intuitive level.
I remember how I got into programming in school - we had these BBC computers which could run BASIC. The language was simple enough for me to understand and intuitive enough for me to actually like programming. (Before that I had seen an aunt learn COBOL and the very look of the language frightened me)
Sure, BASIC is not as advanced as C, BASIC uses GOTO statements, BASIC (not QBASIC though) uses archaic line numbers (but still not as archaic as the Fortran 77 tradition of having to write everything after 7 spaces), but BASIC is the best tool to introduce an enthusiastic person to the world of programming. See this example: In BASIC you would show the person:
10 PRINT "Hello World"
20 END
Bingo, the person magically sees his first program work. Try the same thing with C:
#include
int main(){
printf("Hello World\n");
return 0;
}
See how much more you have to explain? Ever tried to explain stdio.h and int main to someone?
"When the only tool you own is a hammer, every problem begins to resemble a nail." - Abraham Maslow (1908-1970)
All of these can be started as an editor, eg QBASIC / EDCOM
On the other hand, only vers 1.1 can read the dos help file HELP.HLP.
Amusingly, Windows understands what a QHELP file is, that if you click on a quickbasic help file, it says 'this is a DOS help file', whereas any other help file (eg 4dos.hlp), it says "unknown format".
In any case, basic shipped with msdos, because in older times, computers had a rom-basic in their bios.
GWBASIC is a standalone emulator for graphical workstations (ie workstations that replaced the rom-basic with video memory).
BASIC in its raw form continues to affect the way that COMMAND.COM and CMD.EXE work. For example, if one does a test, and it is false, the rest of the line is skipped. In the sample below, we see two statements, separated by an &. If one makes the if statement, one gets neither command, while if the statement is true, both work.
One can implement a die style command by this, or by replacing echo with set, pass a parameter to a subroutine.In any case, it's dodgy.OS/2 - because choice is a terrible thing to waste.
I've never understood why you use a for loop for something like that and not a "while (1)". Can someone clue me in?
while(1) sounds like the Queen talking.
