the expression cannot be a multi-statement.
^ ^ ^ ^ ^ (Output Command)

Description:
1. This command momentarily interrupts program execution and displays alpha
character text or the result of the calculation immediately before it.

press the
w
key during a manual calculation.

two commands.

command.
