DSNE955I `csect-name` COLSUFFIX(YES) WAS SPECIFIED WITHOUT A NAMES PREFIX. COLUMN NAMES WILL BE USED FOR FIELD NAMES

Explanation
 When COLSUFFIX(YES) is specified in a DCLGEN invocation,
DCLGEN generates field names by concatenating the NAMES prefix with
the column names.  However, no NAMES prefix was specified.

System action
 DCLGEN set the return code to 4 and used the
column names as field names.

User response
 This is a warning.  Specify a NAMES prefix when
you specify COLSUFFIX(YES).
