Function keys

Certain functions can be executed simply by pressing a function key. The effects of the function keys depend on how the SDF option FUNCTION-KEYS is set.
There are two assignment modes: the previous ‘Old mode’ (*OLD-MODE) and the new ’Styleguide mode’ (*STYLE-GUIDE-MODE), which offers greater functionality. The terminal type selected in the terminal emulation, however, must support Styleguide mode.

*OLD-MODE
Function key	Effect
	Exit function Exits the current program. A message prompts the user to confirm whether the program should be terminated. During a correction dialog at command/statement entry (see the NO form), the function terminates only the correction dialog. Equivalent to in Styleguide mode.
	Interrupt function Interrupts a current program or a procedure, or aborts output of a command.
	Exit-all function Exits the current program. A message prompts the user to confirm whether the program should be terminated. During a correction dialog at command/statement entry (see the NO form), the function terminates only the correction dialog. Equivalent to in Styleguide mode.

*STYLE-GUIDE-MODE
Function key	Effect
	Interrupt function Interrupts a current program or a procedure, or aborts output of a command.
	Help function Switches to temporarily guided dialog. Equivalent to entering “?”.
	Exit function Exits the current program. A message prompts the user to confirm whether the program should be terminated. During a correction dialog at command/statement entry (see NO form), the function terminates only the correction dialog. Equivalent to in Old mode.
	Exit-all function Exits the current program. A message prompts the user to confirm whether the program should be terminated. During a correction dialog at command/statement entry (see the NO form), the function terminates only the correction dialog. Equivalent to in Old mode.
	Redisplays the last command or statement entered. Equivalent to entering “RESTORE-SDF-INPUT” without operands (default: INPUT=*LAST-CMD or *LAST-STMT).
	Cancel function Exits the current program. A message prompts the user to confirm whether the program should be terminated. During a correction dialog at command/statement entry (see the NO form), the function terminates only the correction dialog.

Note

In Styleguide mode, the function keys ,, andthrough are not supported. Pressing an unsupported function key causes an error message to be displayed.
