Bernie:
The ISTAT functions for mouse location do not operate in Windows R:Base. I have had
success using:
SET VAR vbutton text = (sget(.#FORM_COLUMNNAME,4,1))
Which returns the last button pushed. The sget is necessary because it returns a long
text field with unpredictable contents.
There is also:
SET VAR vbutton = (CVAL('form_field_name'))
but this seems to be designed for the form remaining open. I often set up buttons to
close the form then check to see which button closed it - with that arrangement and
the CVAL function, it returns the current value of whatever form is currently open - I
often have a form within a form.
One of these should solve your problem.
