No. GOSUB was used in very old BASIC. It is an unconditional jump as well. JNZ, JNE, JZ, JE, etc are all conditional. Used when you had to define the line number for each line of code.

eg:

10 GOSUB MYSUB
20 PRINT "Hello 1"

30 SUB MYSUB
40 PRINT "Hello 2"
50 RETURN
55 REM or was it END SUB? Can't remember
60 PRINT "Hello 3"

Would generate
Hello 2
Hello 1
Hello 2
Hello 3

IIRC. This was the state of BASIC programming in Dijkstra's day. Which is probably why he condemned it.

REM is probably for REMOVE (Remove as in remove from code) when compiling

Sub CheckComment
10
if Mid(strLine ,1,3) = "REM" then
comment out
else
end if

Goto 10
End sub

It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration.

True!!!
I hate C++ i cant grasp it , especially when things dont run in steps

huh? maybe its because what i really started in, but it is so logical to me, it does run in steps? unless i misunderstand what u mean by steps??

wanna hate programming, start doing plc stuff, it will make u hate life, i promise.

@supertwit: I never thought I'd recommend this language but Java fits all those requirements. Luckily high performance isn't one of them.

i felt the jump from c++ to java pretty smooth because of the fact that i had done c?? difficult to recommend to some one where to start, since i dunno what its like looking at java if u know nothing else? I felt c was ver eays to use

Umm yes it does but sometimes not

Well to me it seems like it.

Maybe when you start with functions it seems like it's not running Line by line.

In VB things run from Line to the next line until you tell it to got to a
new sub and so on.

Edit:

People can say what they want about VB.

But this has helped me out many times.
I'm in job position Where I.T Stuff is seen as always possible and has to make things work, exactly they way i'm told. Even though i dont do programming for a living, i found ways to solve stuff using VB.

Especially when it comes to Reports, or getting data extracted.

C++ to me is just a bit too much, Not for the Lazy

ok i get what ur saying but i kinda like the fact that u got

function defs

main ()
{

funtion1();
funtion2();
funtion3();

return
}

for me its easy as hell to read and follow, and easy to troubleshoot.
each to his own i guess.

I dont see why people find C/C++ difficult. Its straight forward and simple.

StarPhoenix · Post by **StarPhoenix** » 11 Jun 2007, 18:35

Perhaps a little too cryptic for some?

PHR33K · Post by **PHR33K** » 11 Jun 2007, 18:51

Its cryptic at first, but then again, what programming language isnt. Its confusing at first, but you soon get over it

I've said before why any BASIC variant (including Visual Basic) is for Quiche Eaters; search the programming section and you will find my rants.

I do most of my coding in C# but I do know a bit of C++ (need to get hold of a good textbook so I can teach myself more). C++ is more difficult than C# but is ultimately more powerful. There's a few other languages I'd also like to learn, like Python and Ruby. Given the amount of web stuff that I run (my own website, the FRAG LAN website, a support forum (soon to add another one)), I guess I should really learn some PHP as well.

Mind you, we all may be programming in LOLCODE soon...

Well, like i said, im busy writing a compiler for it

You do realize that they are practically the same language at heart with some syntactical differences, right? I much rather prefer using C# over VB.NET because it is closer to C/C++, which is my language of choice, but it doesn't have any performance / stability or functionality advantage over VB.NET. AFAIK, they sacrificed all those for interoperability that MSIL offers. Unless you know something I don't?

its not difficult, its a waste of time.

I can believe that people still use C++ for application development.

C, C++, C# and java are basically very very simpiler so I guess it probably better to know one of them because its kinda easy to learn the rest (although java is complete OO but still its derived from C).
VB from the little I actually did is pretty good for your standard applications but C++ is far more functional.

No.

Hell, next thing youre going to tell me is that MFC is good

Cure · Post by **Cure** » 12 Jun 2007, 11:12

I didn't say it was great I just said it was pretty good, its simpler then VC++ so for your basic windows applications its perfect, just like I said it's not all that functional, if it wasn't for the .net component I would have like it much it either.
