Reply to note from Fred Weiner <fw1948@xxxxxxxxx> Sat, 1 Jan 2022 16:07:28 -0700 Fred, The syntax you're looking for is: JM 2.clrwQ2 ;*; However, I'm going to echo Edward and suggest that CLRW is not what you want here. The reason CLRW works is that it includes the WINDOW command that Edward suggested. So, you might as well just use WINDOW; to get full screen, a shortened version of the command will suffice: BX window 1Q2 ;*; Alternatively, you can use: SW f;*; (That's func SW, of course.) -- Carl Distefano cld@xxxxxxxxxx
