The first DEFINE command defines PF1 as a key that sets command state
GREEN. The trailing pair of quotation marks is required syntax, indicating
that no command is to be executed when you press this key.
The second DEFINE command defines PF3 as the SHOW STACK command,
but using the /IF_STATE qualifier makes the definition valid only when the
command state is GREEN. Thus, you must press PF1 before pressing PF3 to
issue the SHOW STACK command. The /TERMINATE qualifier causes the
command to execute as soon as you press the PF3 key.
