Answer 1

"good old DOS" is old, but not very good.

Your problem can be solved, basicly by building a temporary .bat file.

It's described in detail here:

I have no DOS available, so I can't test, but this should work for you:

mycommand.exe>c:\temp.txt
find "Serv " c:\temp.txt>c:\temp2.txt

REM init.txt should already exist
REM to create it:
REM   COPY CON INIT.TXT
REM   SET VARIABLE=^Z
REM ( press Ctrl-Z to generate ^Z )
REM
REM also the file "temp2.txt" should exist.

copy init.txt+temp2.txt varset.bat
call varset.bat
for %%i in (%variable%) do set numb=%%i
echo Server number is: %numb%
REM just because I'm curious, does the following work? :
set var2=%variable%
echo var2 is now %var2%

The manual creation of init.txt has to be done once only, if you can live with, that it always creates a variable with the same name (therefore the last two lines, so you could use the same init.txt over and over again - please feedback, whether it works - I'm quite curious)
