Huh? I think you're wrong on this one. A crash won't happen on the lparameters line. Maybe later indeed, but not here. In the case of lparameters, the mdot is of no use.

It assumes a chartype parameter is indeed passed) is about the lparameter line, not about the 'do someroutine' line.

?SQRT("X")VFP does give an error. What should my code do if you improperly pass parameters?
