Using Enterprise COBOL's PROCEDURE-POINTER data item (an IBM extension to the COBOL 85 Standard) in conjunction with the SET statement, you can establish your own condition handling routine using Language Environment-provided callable services. The user-written condition handling routines receive control before the Language Environment default condition handling. You can write user-written condition handling routines in either Enterprise COBOL, Language Environment-conforming C, or Language Environment-conforming assembler.
