No, each dbf record contains both NOMGEO and CONCIS fields.  BEGIN_RECORD
only gets called once per record, not once per field in a record.  If the
dbfawk rules contained "skip" commands then it could go to the next record and
reset things, but that's not the case here.

If the copy of the dbfawk file attached to the original post is accurate, then
I think I see a problem:

BEGIN {
dbfinfo="NOMGEO:CLEBDTC:GENERIQUE:CONCIS:LATITUDE:LONGITUDE:REFERENCE: 
NUMEROSNRC
dbffields="NOMGEO:GENERIQUE:CONCIS"}

The dbfinfo variable value is not terminated with a double quote.  Not sure
*what* dbfawk does when it encounters such a thing --- perhaps its syntax
checking isn't that good.  It should read:

BEGIN {
dbfinfo="NOMGEO:CLEBDTC:GENERIQUE:CONCIS:LATITUDE:LONGITUDE:REFERENCE:NUMEROSNRC";
dbffields="NOMGEO:GENERIQUE:CONCIS"}
 
(i.e. there's a missing double quote and semicolon in what was in the original
post)

If that was a transcription error in the post, then your other suggestion may 
well be the issue:  CONCIS=(Zone.*) will only match if the CONCIS field begins 
with Zone.  If there's any possibility of other characters preceding "Zone"
then one must wildcard, e.g. /^CONCIS=[ ]*(Zone.*)$/ or even 
/^CONCIS=.*(Zone.*)$/
