Here's my problem.

I want to pass a parameter to a form that tells it how to build mycursor.

The called form has a grid whose source is the mycursor.

What I'd like to do is build mycursor in the Load, using the passed parameter so that the cursor exists when the grid's Init occurs.

Unfortunately, VFP6 passes the parameter to the Init of the form ... which as you all know executes after the grid's Init. Thus, I cannot use the parameter in the load to build mycursor.

My quick and dirty fix was to create a variable in the caller's scope that could be seen by the form at Load time. Not the best interface practice, but it works.

Another approach would be to create an empty mycursor in the Load, so that it at least exists when the grid's Init fires, then populate the cursor in the form Init...so how do you create an empty cursor with the desired row/column format?

Are there other commonly accepted ways to handle this situation?
