HANDLE Aid-key [Aid-Key]…;


Aid-Key = {CLEAR | PF1PF12 | PA1 | PA2 | PA3 | ENTER | OTHER }

The HANDLE statement may only be written within a program with INSCREEN(screen) where “screen” is a 3270-type display.  It may not be written within any other logic (IF, CASE, ROUTINE, etc) – Jazz expects you to write HANDLE statements at the start of your logic.


If you have written one or more HANDLE statements then you must finish with HANDLE ENTER.  This must be the last HANDLE statement, and will be where almost all of your program logic will be written.


A HANDLE statement may name several aid keys, e.g.

            HANDLE PF2 PF3;

                        PERFORM Routine1;

is equivalent to

            HANDLE PF2;

                        PERFORM Routine1;

            HANDLE PF3;

                        PERFORM Routine1;


If you combine several AID keys with ENTER, write ENTER first, e.g.

            HANDLE ENTER PF7 PF8;

is valid, but

            HANDLE PF7 PF8 ENTER

is not.


Each aid key may be named only once, e.g.

            HANDLE PF3;

                        Action 1;

            HANDLE PF3, PF4;

                        Action 2;

is invalid.  It does NOT mean that both Action 1 and Action 2 are performed when PF3 is clicked.


When two or more AID keys can cause the same action you can use normal conditional logic like

            IF EIBAID = DFHPF7 THEN;


to distinguish detail which depends on the particular key clicked.




Following a HANDLE the statements following are executed only if the aid key is clicked.  The end of the “HANDLE action” is delimited by another HANDLE statement, or a ROUTINE statement; 


You can consider that, in the absence of explicit HANDLE statement your program starts with

            HANDLE CLEAR

                        Clear the screen, ready for another transaction code to be entered. 

            HANDLE PF3

                        The program will be terminated and control will return to the CICS program that initiated this one.

            HANDLE PF12

                        The transaction is cancelled and

·         If the PROGRAM statement has an EXIT option control is transferred to that program

·         If there is no EXIT option then “Enter Transaction code” is displayed on the screen.  The use can type another four-character CICS transaction code to start the corresponding program.

            HANDLE ENTER [PF7 PF8]

The program’s main logic is performed.  PF7 and PF8 are added if the program detects a multi-record situation, otherwise PF7 and PF8 are treated as OTHER

            HANDLE OTHER

                        Error message “Invalid Function Key”


If you write your own HANDLE condition for one of these AID keys this default handling will be replaced by your logic.
