Mike - thanks for your reply and help.
I tried your suggestions in a simple form to help get a handle on this concept.
I added a property called adata() and in the form's INIT I put:
Dimension adata(2)
adata(1) = 'ONE'
adata(2) = 'TWO'
The properties window shows adata(1,0) on the bottom.
When I run the form I get an error saying "adata is not an array" but DISP MEMO shows the array present.
If I run the form a second time, it runs fine.
What have I done wrong?
Thanks again.
