;This X1 key routine is used for operator entry of
; two different parameters for the thermoformer
; operation. The actual print and read statements
; used are determined by the variable SCREEN, which
; indicates which menu the operator interface is
; displaying.
X1: ;X1 key program

;The X2 key routine is similar to X1 for different
; variables.
