All changes are placed in a work file (utility data set)created by EDIT and are accessible to you if an abnormal termination occurs. Thepurpose of this subcommand is to eliminate the need for specifying the SAVEsubcommand of EDIT to preserve changes.EDIT—CKPOINT subcommand syntax►►CKPOINTCKPvalue►◄EDIT—CKPOINT subcommand operandvaluespecifies the intervals (number of line modifications or input lines) at which acheckpoint is taken. You can use the value operand in one of three ways:1. By specifying a decimal value from 1 to 9999 to be used as the checkpointintervals.2. By specifying a decimal value of zero to terminate interval checkpointing.3. By not specifying a value, causing a checkpoint to be taken. This can bedone even though you have already requested interval checkpointing.Checkpointing does not stop in this case, but continues after reaching thepreviously set interval value.A line is considered modified if it is inserted, deleted, or changed. Issuing theCHANGE subcommand repeatedly and specifying the same line is equivalent tomodifying the line once the CHANGE subcommand is executed.Chapter 1. TSO/E commands and subcommands 93
