Aside from my problems with my own memory, I'm having problems with Xy's.I'm thinking that it may be my (newly instituted) use of lots of long subroutines. are subroutines stored as S/Gs? Could I use U2 (which frame?) to null out each S/Gs after last gosub call to it? Is it better memorywise to use labels and GoLabels instead of subroutines?Thanks.
