There is a 64k limit: msvcrt.inc is ok, setupapi.inc is too long.

Please be more verbose: try a full paragraph explaining what you want to do. Maybe I am just too stupid to understand what you want, but verbosity may help. If English is not your first language, try deepl.com

string2 db 'set "_str=" & echo !_str! & echo %_str%',0

Doesn't look like English. What is your native language? Please formulate a complete, meaningful phrase and let deepl.com translate it, so that we have a chance to understand what you really want.

No, "this string make all clear" НЕТ!

bomz,

You can run ANY executable file with CreateProcess(). CMD.EXE is just a 64 bit executable file.

and how create variable global to two console?

[hutch--]

I don't claim to uinderstand what you are after but creating the same named GLOBAL variable in two apps is easy. You need some method of inter application communication to connect them.

Two (2) techniques,
1. SendMessage using the HWND_BROADCAST message for signalling.

Code Select Expand


        rcall SendMessage,HWND_BROADCAST,PM_COMMAND,0,0

2. Memory mapped files for data.

If one is calling the other, the command line works OK.

I am say about CMD variable. I want create variable inside batch file
masm32 language 100% clear

Code Select Expand

@echo off
setvar
echo %newvar%
pause

I am creating batch file now and have problem to create global variable standard methods because number of iterations to big inside cycles. So it is not so easy as may seem

What about using the /P option?

C:\>echo abc >tmpfile & set /P newvar= <tmpfile

should result in "newvar=abc"

much better but how do it without TMP file
echo abc|set /p bewvar=

CMD.EXE have SETX command and can be problematic.

echo abc|set /p bewvar=

You're right, this "should" work, but obviously does not.

As a workaround, perhaps you might use FOR:

c:\>for /F %i in ('echo bomz') do set newvar=%i

I am exactly want make utility which allow avoid FOR such cases
