VFP 8 documentation states that the maximum nuimber of parameters that can be passed to a procedure is 26. I have always thought that the parameters restriction was a bit rough, and have hoped that it would one day increase.

I thought I might test this with VFP 8 and PROCEDURE and FUNCTION calls. I found that it was possible to pass 27 parameters to a FUNCTION, and a lot more to a PROCEDURE.

Can anyone comment on this? Is their no limit to parameters into a PROCEDURE because they are passed by reference?
