POP
Syntax:
POP variable [,variable,...]
Function:
Takes a value PUSHed to a stack and assigns it to the variable.
Mode:
Command, run
Use:
POP X,Y,Z
DESCRIPTION
Multiple variables can be POPped off the stack by separating the variables with commas. The first value
POPped is the last value PUSHed.
POP and PUSH are useful for transferring data values between subroutines. They allow you to write a
subroutine with arbitrary variable names. Data transfers to and from the subroutine can be performed by
PUSH and POP, rather than by equating variable names.

ERROR
