Use the following call:
call x"AF" using       set-map-byte
                       adis-key-mapping 
 
	 where set-map-byte and adis-key-mapping are defined in the Working-Storage Section of your program as follows:
01 set-map-byte pic 9(2) comp-x value 3. 01 adis-key-mapping. 03 adis-map-byte pic 9(2) comp-x. 03 adis-key-number pic 9(2) comp-x.
where:
The following code changes the action of the Backspace key (key number 14) to simply move the cursor to the left (function 3), and changes the Tab key (key number 8) to perform the Tab function (function 8):
* Change mapping of Backspace key
     move 14 to adis-key-number
     move 3 to adis-mapping-byte
     call x"AF" using set-map-byte
                      adis-key-mapping
* Change mapping of the tab key
     move 8 to adis-key-number
     move 8 to adis-mapping-byte
     call x"AF" using set-map-byte
                      adis-key-mapping
