DEVELOPER |
 |
User-defined Function Keys 33 to 232 can be used by GUI terminals, their numbers can be used as actions associated with s and icons. Function Keys greater than 232 are reserved for PROIV.
In summary:
-
Internal Function Keys are -2 to 32, then 233 and above.
-
User-defined Function Keys are 33 to 232.

Note: There was a change with internal Function Keys when PROIV moved from Version 5 to Version 6. The internal Function Keys were shifted up by 40 and you may have to amend your code accordingly. |
The following table lists the internal Function Keys and their associated @FNKEY values. They can be interrogated using the System Variable @FNKEY. For User FKEYn, the @FNKEY value is n + 32.

*1 Sends just RETURN when there is no or icon response string (i.e., does not send format text).
*2 Specifies no Function Key (this allows two or more or icon response strings to be concatenated before being activated). This is also useful for icons with no associated actions.
