IEBDG (Test Data Generator) Program

IEBDG is a data set utility that is used to provide a pattern of test data to be used as a programming debugging aid. This pattern of data can then be analyzed quickly for predictable results.

You can create a data set without supplying any input data, or you can specify a data set from which input data is to be taken. The data set that you create may have records of any format. Sequential data sets, or members of partitioned data sets or PDSEs, can be used for input or output.

IEBDG also gives you the option of specifying your own exit routine for monitoring each output record before it is written.

When you define the contents of a field, you must decide:

Which pattern is to be placed initially in the defined field. You can use your own pattern, or a pattern that is supplied by IBM.
What action, if any, is to be performed to alter the contents of the field after it is selected for each output record.

If IEBDG is invoked from an application program, you can dynamically allocate the data sets by issuing SVC 99 before calling IEBDG.
