FILENR <= 2     {CNT++
                 CHFM[CNT] = $1
                 RGEX[CNT] = $2
                 DOTS[CNT] = $3

Thanks RudiC. Adding new fields at the end will work too.
But, I am not getting desired output for below input -
Code:
$ cat RECORD
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDD.HHMISS.YYYY-MM-DD.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDD.HHMISS.YYYY-MM-DD.XXXXXXXXXX.txt|ABC_123_V01P.YYYY-MM-DD.YYYYMMDD.HHMISS.XXXXXXXXXX.txt|CATEGORY
SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY
