12.5 SAA/CUA Function Key Assignments

When a new LANSA partition is being defined to conform to SAA/CUA standards (or an existing one is being modified), you are asked to define what standard function key assignments are to be used and what the Short Form description of the function key is to appear on all generated screens.

The table below indicates the standard function key assignments used by the LANSA implementation under SAA/CUA, the suggested Short Form descriptions and the suggested Function Key that should be assigned.

Like the panel attributes facility, you are not forced to follow the recommended values and can change them to your site standards if desired.

Notes about this table:

Re = denotes an SAA/CUA "reserved" function key. In such cases the function key cannot be reassigned to other functions, even if the specified functions don't apply to a particular panel.

Op = denotes a "non-reserved" SAA/CUA function key. In such cases the function key may be reassigned to other functions, but only if the application does not support the functions prescribed for the function key by this table.

* = denotes an SAA/CUA function key assignment that is prescribed for complete SAA/CUA compatability, but is not currently implemented directly within LANSA. The use of such keys is controlled by the USER_KEYS parameter of DISPLAY, REQUEST or POP_UP commands. It is the responsibility of the user to implement such key assignments in RDML programs as per the SAA/CUA guidelines described by the table.

*** = denotes a non-SAA/CUA proscribed function key that is required in this table because it is implemented by LANSA.
