Hi friends,

Here is a simple command line parser algo, it can handle quoted parameters. I coded also a tiny C run-time startup module using my algo to get command line parameters. The zip file includes examples for Digital Mars , Pelle's C and Visual C/C++ compilers.

ParseCmdLine PROC uses esi buffer:DWORD
