Finding and correcting errors in your data

To find errors in your data (without correcting them), you can enter the FE (Find Error) primary command. This finds the following types of errors:

Numeric fields whose contents cannot be formatted as a valid numeric value
Fields that run over the record length

When you enter the FE command, File Manager positions the cursor at the beginning of the field in error and, if necessary, automatically scrolls the data to bring the field into view.

To move the cursor to the next field in error, either enter the FE command again, or press the RFind function key (F5).

To find and change numeric fields flagged as being in error (all asterisks in the field display) to a specific numeric value, use the CE primary command.
