Use the OVRDBF command to update files

Use the OVRDBF command to create a program that updates files without really updating.

I have found the INHWRT (inhibit write) parameter in the OVRDBF extremely useful when testing a program without wanting to update any data. When set to *YES, the processed records are prevented from being written to the database, however the records WILL be written to any output device specified. This is perfect when you need a list of those records that will be modified before the database is actually changed. Once the list is verified, you can rerun the program without program changes or recompiling.
