HP50G help as POP command —> insufficient memory

[Gil]

Yes for the length in such an easy case.

But PUSH and POP will be shorter if at the end of your program you have more than two outputs,
requiring a «RCLF SWAP [...] # Roll STOF»,
with # standing for 4,5,6 asf.

Or if, in the middle of a program, you have several stacks level occupied (and say only one final stack level occupied).
Then «RCLF # ROLLD [...] SWAP STOF» will have more bytes than PUSH and POP,
again with # standing for 4, 5, 6 asf.

Besides, PUSH and POP commands save directory path, which can be useful when moving into a different directory inside a program. Then, that combination of commands is shorter.
