REVERT statement cancels the existing ON unit for the specified condition.

Answer / nandish shanabog c s

Few (though NOT ALL) ON unit can be disabled using NO<ON_UNIT_NAME> at the program level (at MAIN PROC), or procedure level or for a particular statement in PL1 program.

Example:

1.
To disable ENDFILE on-unit in your entire program, you may code as below:

(NOENDFILE):
MAINPGM: PROCEDURE OPTION(MAIN);

2.
To disable a on-unit for a particular procedure:

(NO<ON_UNIT>):
PROC1: PROCEDURE;

3.
To disable for a particular statement:
(NO<ON_UNIT>):
STATEMENT;
