Solving several problem at once using command line

[Rasheed]

Hi everyone

I tried to solve several problems (or instances) using this batch :

set $dir="C:\Program Files\MiniZinc\"
pushd %$dir%
@echo off
for /l %%i in (50, 50, 100) do (
    for /l %%j in (7,3, 10) do (
for /l %%w in (1,1,10) do (
set filename=N10D%%iA%%jK%%w.dzn
set filename2=R_N10D%%iA%%jK%%w.txt
minizinc --solver Chuffed "CPMODEL.mzn" "C:\Users\Sony\Data1\%filename%"  -t 10000000 --output-time -o "C:\Users\Sony\Results\%filename2%"
)
    )
)

popd
pause

Unfortunatly I'm getting the following errors :

C:\Users\Sony>set $dir="C:\Program Files\MiniZinc\"

C:\Users\Sony>pushd "C:\Program Files\MiniZinc\"
minizinc: Unrecognized option or bad format `C:\Users\Sony\Data1"  -t 10000000 --output-time -o C:\Users\Sony\Results"'
minizinc: MiniZinc driver.
Usage: minizinc  [<options>] [-I <include path>] <model>.mzn [<data>.dzn ...] or just <flat>.fzn

Thanks for your help !

This is because in batch files the expansion of the %filename% variables happens immediately (because the for loop with its contents is one command - the variables get expanded before starting the loop).

You can try something like:

set $dir="C:\Program Files\MiniZinc\"
pushd %$dir%
@echo off

SETLOCAL ENABLEDELAYEDEXPANSION

for /l %%i in (50, 50, 100) do (
    for /l %%j in (7,3, 10) do (
for /l %%w in (1,1,10) do (
set filename=N10D%%iA%%jK%%w.dzn
set filename2=R_N10D%%iA%%jK%%w.txt

minizinc --solver Chuffed "CPMODEL.mzn" "C:\Users\Sony\Data1\!filename!"  -t 10000000 --output-time -o "C:\Users\Sony\Results\!filename2!"

)
    )
)
popd
pause

Thank you,

Great ! Thanks a lot Jason for your help !

I had to put the entire path of the "CPMODEL.mzn" file in ordrer to avoid another error.

Thanks to Jip also for your suggestion.
