The bug is in the statement

static char Ofldnames[OUT_ARG_MAX][FLDNAME_SZ] =

This should be

static char *Ofldnames[OUT_ARG_MAX] =

This will be fixed in next release of BASE.

Incidently the calcRecord, dfanoutRecord, gsubRecord, palRecord, selRecord,
and subRecord.c all had a similar statement. The others worked only because
the field names referenced are less than 4 characters in length and are thus
null terminated. All will be written correctly in the next release.
My guess is the the subRecord started the problem and all the other record
types copied from it.
