Erik,
Thanks for your reply.

I dont know what the code is going to be until Runtime, so I cannot pur them into a class beforehand.

In the past, I have ameded reports by copying the .frx to a temporary .frx, then amending it and then printing the report.

I wonder could I do something similarly with a .SCX form file. i.e. copy the scx to a Temp.scx, manipulate this file(which is really only a dbf) , Compile it and then DO FORM Temp.

Regards,

Gerard
