Command Line Parameters on an EXE

[ssimop]

I want to use a file's right context menu entry to invoke, using this file, a qm .exe file, namely :
Registry entry : "C:\Documents and Settings\SES\My QM\Exe\GoToAFJ_Exe.exe" "%1"

I envisage a difficulty in obtaining the file's path (%1 above) in macro GoToAFJ_Exe. Any advice is welcome.
