Thanks for previous replies,
I changed my code and was more careful with all the pushes and pops! but my code still doesn't work, instead of the second subroutine returning to the first subroutine, it returns to the very beginning of the main program code.

could this be because I make use of the accumulator during the subroutines?

again, all help appreciated!!
