QRG5008

The factor 1 field-name entry (positions 18-27 of a calculation specification) is not valid if its first character is not alphabetic (A-Z, @, $, or #), OR it is not left-justified, OR it contains embedded blanks OR it contains characters that are not valid, OR it contains a field name or variable-index name that is longer than six characters.

Correct the factor 1 field-name entry in positions 18-27. Compile again.
