I am writing a program in Turbo C and would like to know how to pass
arguments to it from the command line after it is compiled to a .exe file.
I have tried:
main(arg1)
char *arg1;
{
......
/* do something with arg1 here */
.....
}
Unfortunately, the program doesn't seem to recognize arg1. If I pass it a
string arg1 is just empty. Any help is appreciated. I just want to pass a
string to the program.
Thanks in advance,

Hope that will work in Turbo C. -dan.

[simple mistake deleted] Did a new semester just start? I know, I'm just as guilty of wasting bandwidth with this followup, but I just can't help it. Seems like an unusually large bunch of these types of articles lately. I'm especially diamayed by this in comp.lang.c, which has generally been remarkably free of blatant beginner's mistakes.

(By way of atonement for my own sins, I sent a pleasant response via email to the party above. S/He probably knows more about argc,argv now than s/he originally wanted to know.)) -- Carl Paukstis +1 509 927 5600 x5321 |"The right to be heard does not | automatically include the right UUCP: carlp@iscuvc.ISCS.COM | to be taken seriously." ...uunet!iscuva!carlp | - H.

Try main (argc, argv) int argc; char *argv[] Then argv[0] will hold the command name, argv[1] will hold the first argument, etc. As far as I know, there's no definition for what makes an argument, but in Unix, it's a word separated by white space. Oh, argc will hold the number of arguments (including the command name). For more information, check K&R1 5.11 (p110-114) or K&R2 5.10 (p114-118). If someone knows Turbo C better than I do, tell me if that will work.... -- Andrew Barnert (Andy Social/Andy Christ/Andy Matter/ex-God) ins_balb@jhunix/ins_balb@jhuvms/c08_d103@jhunix The opinions expressed in this message are yours.

To the previous poster, though, why didn't you consult your reference manual? It's clearly stated how to access parameters passed on the command line via the argc/argv combo.
