ENABLE Reference Manual

ENABLE FUNCTION KEYS
Special Operations
DEFINE PRINTER (SF4)
A DEFINE PRINTER operation defines the terminal, printer, or
process that is to receive the current screen image. When you
request a DEFINE PRINTER operation, the application displays a
prompt on line 2 of the screen. You must then enter the name of
the terminal, printer, or process and press SF4 again.
PRINT (SF5)
A PRINT operation prints the current screen image on the
terminal, printer, or process defined with a previous DEFINE
PRINTER request. The application displays a message while
performing the PRINT operation.
RECOVER SCREEN (SF15) Operations
When the application performs a RECOVER SCREEN operation, it
redisplays data items stored in the working storage area of the
application. These data items might not necessarily correspond
to values that were on the screen at the time that you requested
the RECOVER SCREEN operation.
Special Operations (SF3 and SF6)
ENABLE reserves two function keys (SF3 and SF6) for users. To
activate these function keys, you must modify the SCREEN COBOL
source code after application generation.
If the SCREEN COBOL source code has not been modified to make use
of these keys, the application returns a message stating that
the keys are not supported when you press either SF3 or SF6.
If these keys are active, their purpose is application dependent.
