>>Yes, you put LPARAMETERS or PARAMETERS as the first statement in the .Init() method of the form. Another useful technique is to save the parameters to form properties (which you predefine), so they don't go out of scope when Init() ends e.g.

I updated my reply before you posted yours, basically you don't need the "@"s in your command, DO ... WITH ... passes variables by reference by default without needing them. So just,
DO FORM junkform WITH parm1, parm2
