Function Key Assignments - 6520/6530 Screen

RETN Returns to the named or previously called requester (if a specific
requester is not named). Each requester can have many named RETN
keys and many unnamed RETN keys (although having only one
unnamed return key is most common). There are 24 function keys
available for use on the 3270 terminals, and 32 keys available on the
Tandem 6520 and 6530 terminals.
If you enter a requester name in the Requester/Service Name column,
that requester must be in the call stack of the requester for which this
Function Key Assignment screen refers. For example, if the requester
is X and your application has this structure:
A
/ \
B C
/ \
D E
/
X
X can specify a return to A, B, or D. X should not specify a return to C or
E.
If you name the entry menu (A in this example) as the Requester/Service
here, you have specified the equivalent of the SF16 key in the Pathmaker
product.
If you leave the Requester/Service Name column blank for this key, the
RETN key returns to the requester from which this one was called (D in
this example), as F16 does in the Pathmaker product.
SEND Invokes a service by sending an service request message to the named
service. Name the service you want to invoke in the Requester/Service
Name column and later match its parameters in the SEND Parameter
Definition screen by using F10. You cannot use SEND from a MENU or
DB requester.
USER Use this action to designate a function key that is to be entirely controlled
by SCREEN COBOL code that you write. You must include the SCREEN
COBOL code for the function key in the ?SECTION USER-PRE-
function-key and ?SECTION USER-POST- function-key sections of
the requester copy library for this requester. The Pathmaker product will
generate only minimal code for a function key associated with the USER
action.
