Shell command and variables 1

This example passes two parameters to C:\test.bat

QB 4.5 code:


test.bat:

Hope this helps.

line input "Enter parameter for program ";Var$
shell "C:\File.EXE "+Var$
The space after exe will be mandatory. If it requires
a "/" character then
shell "C:\file.exe /"+Var$

EXECUTE THE ".BAT" FILE AS SPECIFIED BY FREESTONE

THEN

In the bat file code

SET MYPARM1=%1
SET MYPARM2=%2



THEN RUN THE PROGRAM WITH THE FOLLOWING CODE AT THE BEGINNING

MYFIRSTPARM$ = ENVIRON$("MYPARM1")
MYSECONDPARM$ = ENVIRON$("MYPARM2")

NOW THE QBASIC PROGRAM CONTAINS THE PASSED STRINGS AS MYFIRSTPARM$ & MYSECONDPARM$ .


Computer thought: I teach a lot of programming so I can learn. You can never learn it all.

thank you all!!

I did it with Buff1 advice, thank you all for your interest.

now i've got another issue,

i'm getting "illegal function call" error i guess that's because the commandstring in the SHELL is too big, is there a way to fix that?

thanks again!

It would help if you could post some of the failing code.

I doubt that it's too long unless it's over 256 characters.
I would more likely look to an error in the code.

Without at least a snipet though, we are unable to say for
sure. Like saying "I sneezed -- what's wrong with me?"
and expecting the exact diagnosis.

Another thought: when you shell to another program/bat file the current environment is passed straight through so the values can be retrieved directly by the shelled program.

you used to be able to increase the set area in the cmd box up to 4k that you run the programs in. look in the system for that possibility, maybe use the properties folder on the cmd icon. Maybe it is in the windows equivalent of autoexec of config files . Sorry I don't have the time right now.
