Batch Loop menu (multiple selection)

Question

I'm trying to set up a batch menu that allows for multiple selection at once then runs all the functions. Sequence that functions are not relevant just the fact that the functions will be run with out, outside errors. Here is the code that I have so far.

@Echo off
Echo Please Enter the corrasponding numbers separated by a space or colon (,) 
Echo for the Options that you would like to run e.g. 1 4,3 2
Echo Option #1 
Echo Option #2  
Echo Option #3  
Echo Option #4
Echo.

SET /P Selection=Please Select Restore Options? 
echo You chose: %Selection% 

setlocal ENABLEDELAYEDEXPANSION
Set /a index = 0
FOR %%A IN (%Selection%) DO (
SET Array[!index!] = %%A
SET /a index += 1
)

for /F "tokens=2 delims==" %%s in ('set Array[') DO (
set string=%%s
set string=%string: =%
echo %string%
Call :Opt%string%
)

pause
goto :EOF


:Opt1
ECHO Option 1's code
GOTO :EOF

:Opt2
ECHO Option 2's code
GOTO :EOF

:Opt3
ECHO Option 3's code
GOTO :EOF

:Opt4
ECHO Option 4's code
GOTO :EOF

The code I have works to the point where trying to call the Array veriable and attach it to a Call e.g. Call :Opt%%s The probelm I have is that the array variable keeps coming out with a space proceeding the selected variable. So I have tried combating this with set string=%string:=% but I keep getting an error.

Error :

either echo is off and only opt is getting called with out the selected variable.

Help with this would be amazing, Thanks in advance.

Answer 1

The start of the problems is

SET Array[!index!] = %%A
------------------^-^---- = aditional spaces

This aditional spaces are used, so you end with a variable with an aditional space in its name and an aditional space in its value. So, better use

SET "Array[!index!]=%%A"

The reason for the echo error is you forget to use delayed expansion in the for %%s loop. You change the %string% variable inside the loop and try to use the changed value inside the same loop.

for /F "tokens=2 delims==" %%s in ('set Array[') DO (
    set "string=%%s"
    set "string=!string: =!"
    echo !string!
    Call :Opt!string!
)

But the corrections indicated in the original set make it unnecessary to replace the spaces.
