Michel,

So launch the EXE with one string that encompasses all the parameters and parse it apart in VFP:

TheAPPWithLotsoParameters "1 2 3 4 5 6 7 a b c d e f g h i j k l m no pq rs tu v w x y z is this enough arguments for you? *bg*"

You'll get just one string parameter that you can alines() apart into each parameter.

>Yes, this is also another good approach. But, there are too many possibilities of launches from that EXE that it has to be from a command line.
