Thank you Don. I checked gawk code in field.c - routines for dealing with fields and record parsing.

So record parsing happens first with default field separator, then new field separator is used to parse subsequent records.

I also noticed that function set_NF is called before record parsing. So gawk behavior for this variable is different.
Code:
awk -F, '{NF=1}{print $NF}' dafile
10.10.10.10
10.10.10.11
10.10.10.12
10.10.10.13

Any idea why developers didn't do the same with function set_FS

NAME
dbf_dump - Dump the record of the dbf file FORMAT
dbf_dump [options] files where options are --rs output record separator (default newline) --fs output field separator (default colon) --fields comma separated list of fields to print (default all) --undef string to print for NULL values (default empty) --memofile specifies unstandard name of attached memo file --memosep separator for dBase III dbt's (default x1ax1a) --nomemo do not try to read the memo (dbt/fpt) file --info print info about the file and fields with additional --SQL parameter, outputs the SQL create table --version print version of the XBase library --table output in nice table format (only available when Data::ShowTable is installed, overrides rs and fs) SYNOPSIS
dbf_dump -fields id,msg table.dbf dbf_dump -fs=' : ' table dbf_dump --nomemo file.dbf ssh user@host 'cat file.dbf.gz' | gunzip - | dbf_dump - DESCRIPTION
Dbf_dump prints to standard output the content of dbf files listed. By default, it prints all fields, separated by colons, one record on a line. The output record and column separators can be changed by switches on the command line. You can also ask only for some fields to be printed. The content of associated memo files (dbf, fpt) is printed for memo fields, unless you use the "--nomemo" option. You can specify reading the standard input by putting dash (-) instead of file name.
