Gary; Yes, what is preceived as ugly is often powerful. This is the construction of the called routine with the name of the argument(s) dynamically generated. I say argument(s) because VarName could be of a form, "P1,P2,.P3" and is the routine was constructed properly, then the argument list would have been; D MyFunct2(.P1,P2,.P3) Now we hope everyone has read ahead and knows about the period in front of P1 and P3. These are "call by name" an not "call by value" as is P2. Results can be returned via P1 and P3, but only the value of P2 is exposed. Has that sufficiently confused everyone? Confusion is the beginning of enlightenment.
