Add a PARAMETERS or LPARAMETERS statement as the first executable line of your main .PRG file (or the Init() of a modal form if you start your app from a modal form.) VFP will accept command line arguments as strings. if a string passed on the command line needs to contain a space or other delimiter, the string needs to be contained within double quotes " or the command line parser will pass the parameters as several arguments eg:

LPARAMETER uArg1, uArg2, uArg3, uArg4, uArg5, uArg6

MYApp.EXE Mary had a little lamb

will get 5 parameters filled (PCOUNT() = 5)

MyApp.EXE "Mary had a little lamb"

will get 1 parameter (PCOUNT() = 1).

Some command line switches will be stripped by the VFP engine, so avoid the use of - and / prefixing of arguments if at all possible.
