Hi,
Is it possible to use the output that is echoed by a command in DOS 7.1?. The for /f does not exist in 7.1.
I use the find command:
type file.txt|find "string" /c
It returns me a number.
I can send the result to another file like this
find "string" < inputfile > outpufile
But i need to send it to a variable.
Thanks for the help.

You could use SET2VAR.EXE
$MAC now contains the result, in your situation you'll need type "$file" |set2var $var
SET2VAR.EXE can be found inside the netbootdisk http://netbootdisk.com/
You could use SET2VAR.EXE
Code: Select all
"%Drive.RAM%\SHOWMENU.EXE" Finding MAC Address
rem ::(
"%Drive.RAM%\NBMAC.EXE"
"%Drive.RAM%\NBMAC.EXE" |> "%Drive.RAM%\OUT.BAT" "%Drive.RAM%\SET2VAR.EXE" MAC
rem ::
call "%Drive.RAM%\OUT.BAT"
rem ::)

Re: DOS 7.1 Use command output in variable
This seems to be totally what i'm looking for but i am not able to make it work.
I use this simple command:
type allo.txt|find "1.10" /c|set2var cnt
it work and echo @set cnt=2 but im in the same problem as before, i still can't use the value of cnt in a command.
I need to write:
Type cnt
to see the value.
the command echo %cnt% tell me echo is on instead of 2.
I'm new to Dos so i probably did something wrong but can't figure it out.

The guy from NetBootDisk wrote Set2Var himself, he also ownes the copyright.
What you are looking for is explained at his site.
set2var was designed in such a way that it writes set $var=? to TempBatchFile.bat.
The only thing you need to do now is call TempBatchFile.bat.
It's really easy to write your own Set2Var.EXE application. It only takes about 5 assembly instructions.
Unfortunately I have zero knowledge of the x86 instruction set.
I hope to learn this myself someday or be teached by someone.
Does anyone know a good x86 ASM forum ?
Beware, DOS 7.1 was designed to do simple scripting only. Did you know it supports QBASIC.
The MS installer was written in it. It's a powerfull language and a lot of fun.
If you like scripting, QBASIC supports it
