Loading Terminal Function Keys - Overview
PRO/5 lets you load function keys and edit keys on terminals. When the user presses a function or edit key, it enters a string into the input buffer. For example, if you load function key 8 (F8) with the string "END", the user can press F8 instead of typing END and pressing the ENTER key. Use the 'FL' (function load) and 'EL' (edit load) mnemonics to load function keys and edit keys. These mnemonics also return information about the function keys such as the number of keys available, their current status, and so on. All information returned to the program is put into the input buffer and must be read by the program.
