Batches as Functions

[yossi_moses]

I thout about seperating code between files and use them as functions.
I had many errors until I realized that the Output of this Funcs must be only the 'ECHO ...' that I need.
In these file there must be @ECHO OFF in its 1st line, otherwise each line code become an Output.
Here is a little example. even recursive:
Let's have file Named Func.CMD
We call it from Command-Line with a parameter:

Code: [Select]

CALL Func.CMD 1The code in Func.CMD:

Code: [Select]

@ECHO OFF
SET /A X = %1 + 1
IF %X% LSS 10 FOR /F "DELIMS=" %%i IN ('CALL Func.CMD %X%') DO SET /A X = %%i
ECHO %X%

It looks so:
C:\>CALL Func.CMD 1
10

I hope someone can enjoy it

This can be useful, but its hard to pass things out.

Something like this might work.

Code: [Select]

Setlocal enabledelayedexpansion
Set param_num=0
For %%a in ('call func.bat %param1%') do (
Set param_!param_num!=%%a
Set /a param_num+=1
)
