HELP For Atari XL And XE
I have an Atari 800XL and would like to know how to read the HELP key.

The status of the HELP key can be determined by PEEKing location 732 on the Atari XL and XE computers. If the HELP key alone is pressed, this location returns a value of 17; when SHIFT and HELP are pressed simultaneously, it contains 81. Pressing CONTROL and HELP returns a value of 145. The statement POKE 732,0 clears location 732, so you can check for subsequent keypresses.
