GRS6018

An Indicator-Negation entry is specified (position 23, 26, or 29), but no indicator is specified in the corresponding Output-Indicator entry (positions 24-25, 27-28, or 30-31). The Indicator-Negation entry defaults to blank.

Remove the Indicator-Negation entry, or specify a valid indicator in the corresponding Output-Indicator entry. Compile again.
