The DDS for the MAINMENU display device file specifies file level entries
and describe one record format: HDRSCN. The file level entries define the
screen size (DSPSIZ), input defaults (CHGINPDFT), print key (PRINT), and a
separate indicator area (INDARA).
The HDRSCN record format contains the constant 'CUSTOMER MAIN INQUIRY',
which identifies the display. It also contains the keywords TIME and DATE,
which will display the current time and date on the screen. The CA keywords
define the function keys that can be used and associate the function keys
with indicators in the RPG program.
