HP49-50G: HALT command as assigned key?

[Joe Horn]

Here's one way to put a bare HALT on the stack. Put { HALT } on the stack. Then execute 256.03 MENU and press COMP→ DROP COMP→ DROP.

The first COMP→ DROP leaves the System RPL program :: xHALT ; on the stack. The second COMP→ DROP explodes the program and leaves the xHALT by itself.

EDIT: A simpler way to get what you want is to simply assign " HALT " to a key.
