Hi, I would like to pass a commandline argument to another batch/exe, it looks like this: start filename.exe mod=something "mod=something" is ONE SINGLE command line arg, that canNOT be changed in the app it's being sent to if I send it to another batch file to test the output I get now, then %1 is set to "mod" and %2 is set to "something" but I need %1 to be "mod=something" how would I do this?

In the batch that accepts your parameter code %* to get the full command tail, i.e. First batch call second.bat mod=something Second batch start filename.exe %* obviously in that way you can pass just one parameter on the command line.

@echo off set mod=mod=something start filename.exe %mod%

thx, hadn't tried that yet it's still not 100% though, you need to put it between quotes for it to work, otherwise the "=" character and everything that follows it is not stored in the variable so this is what I did, and now it works: @echo off set mod="mod=something" start filename.exe %mod%
