Dragan,
I've only used the IN maybe once or twice in the last few years. I don't think there is an equivalent in function call notation, other than SET PROC.
Also must remember that DO func passes references, what func() passes depends on the setting of UDFPARMS but the FoxPro library code like GENXTAB in FPW2.x can fail horribly and it's pretty hard to detect why it failed when UDFPARMS is changed from the default setting.
>Anyway, if "do the_prg with param1, param2" is equal to the function call of "=The_prg(param1, param2)", what is equal to "do the_prg in prg_file with param1, param2"?
