Do you mean you have a window that contains a subfile?
If so, adjust the values in the WINDOW keyword that is associated with the subfile.
Right .. WINDOW(Row column height width)
So the first two values locate the upper left corner
the third is the number of rows including the boarders (available is height – 3 (2 boarders and message)
the fourth is the number of columns including the boarders (available is width – 2 (boarders)
You’re subfile control record may contain the window keyword containing the name a window record. It’s that window records window keyword that needs to be changed.
