Thanks RudiC. This works perfectly well for me.
If I can ask for one more thing that arise with this result. Now, with the same three input files RECORD, date_format.csv and timestamp_format.csv, I need to group how many dates are in column 4 and 5.

For example, If the RECORD file has records -
Code:
$ cat RECORD
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY
SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY
$

Output should be -
Code:
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY|2|1|1|1
SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY|1|1|1|1

where,
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEG ORY and SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY represents the input record.

Next 2 columns 2|1|1|1 represents, number of date and time fields which is part of date_format.csv and timestamp_format.csv in fields ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt and P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv i.e. column 4 of input file RECORD.
and Next 2 1|1|1|1 columns represents, number of date and time fields which is part of date_format.csv and timestamp_format.csv in fields ABC_123_V01P.YYYYMMDD.HHMISS.txt and Report.ABCD_csv.YYYYMMDD.HHMISS.csv i.e. column 5 of input file RECORD.

So you want to print out info ACROSS lines, i.e. in line 1 should appear info about field 4 of line 1 and 2, and in line2 there should be info on field 5 of line 1 and 2? What if more lines will appear, i.e. line3, line 4, etc.? Where and how should those infos be printed?

Hi RudiC,

Let me explain why and what I am looking exactly.

For input file RECORD, earlier code provided by you provides below output -

Input File -
Code:
$ cat RECORD
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY
SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY
$

Output -
Code:
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY|9|8|YYYYMMDD|........|%Y%m%d|26|6|YYMMDD|......|%y%m%d|32|6|HHMISS|......|%H%M%S|14|8|YYYYMMDD|........|%Y%m%d|23|6|HHMISS|......|%H%M%S
SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY|17|8|YYYYMMDD|........|%Y%m%d|26|6|HHMISS|......|%H%M%S|17|8|YYYYMMDD|........|%Y%m%d|26|6|HHMISS|......|%H%M%S

Here, As you can see in input file for 1st record column 4 filename is ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt which contains 2 date values (as specified in date_format.csv) and 1 time value (as specified in timestamp_format.csv).
For 2nd record column 4 filename is P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv which contains 1 date value (as specified in date_format.csv) and 1 time value (as specified in timestamp_format.csv).

Similarly, For column 5 we have different number of date/time values. Which results in different number of columns in output depending on number of date/time values in filename. Hence, It is difficult to identify exact position of date/time variables for column 4 and 5.

For this reason, I was thinking of adding 4 more columns in output which will help me to identify how much date/time variables present in column 4 and 5.
Code:
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY|2|1|1|1
SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY|1|1|1|1

Here, For 1st output record, 2|1|1|1
-- 2 represents number of date variables in columns 4 as specified in date_format.csv
-- 1 represents number of time variables in columns 4 as specified in timestamp_format.csv
-- 1 represents number of date variables in columns 5 as specified in date_format.csv
-- 1 represents number of time variables in columns 5 as specified in timestamp_format.csv
For 2nd output record, 1|1|1|1
-- 1 represents number of date variables in columns 4 as specified in date_format.csv
-- 1 represents number of time variables in columns 4 as specified in timestamp_format.csv
-- 1 represents number of date variables in columns 5 as specified in date_format.csv
-- 1 represents number of time variables in columns 5 as specified in timestamp_format.csv

Hope this clarifies why I am looking for this. It will be even better if we can use our earlier code and produce output as below -
Code:
SOURCE|LOGIN|SERVER|ABC_123_YYYYMMDD_V01P1234YYMMDDHHMISS.txt|ABC_123_V01P.YYYYMMDD.HHMISS.txt|CATEGORY|2|1|1|1|9|8|YYYYMMDD|........|%Y%m%d|26|6|YYMMDD|......|%y%m%d|32|6|HHMISS|......|%H%M%S|14|8|YYYYMMDD|........|%Y%m%d|23|6|HHMISS|......|%H%M%S
SOURCE|LOGIN|SERVER|P_XYZ_1234_ABCD.YYYYMMDD.HHMISS.csv|Report.ABCD_csv.YYYYMMDD.HHMISS.csv|CATEGORY|1|1|1|1|17|8|YYYYMMDD|........|%Y%m%d|26|6|HHMISS|......|%H%M%S|17|8|YYYYMMDD|........|%Y%m%d|26|6|HHMISS|......|%H%M%S

Here, column 7,8,9 and 10 will serve the same purpose as mentioned above to represent number of date/time variables in column 4 and 5 respectively.

That's much clearer, thank you. How about (adding the new fields at the end, so we can print the format info as we go through the file)
Code:
awk '
FNR == 1        {FILENR++
                }

FILENR <= 2     {CNT++
                 CHFM[CNT] = $1
                 RGEX[CNT] = $2
                 DOTS[CNT] = $3
                 FMTS[CNT] = $4
                 FIDX[CNT] = FILENR
                 next
                }

                {printf "%s", $0
                 for (j=4; j<=5; j++)   {TMP = $j
                                         PTR = 0
                                         for (i=1; i<=CNT; i++) if (match (TMP, CHFM[i]))       {printf "|%s|%s|%s|%s|%s", PTR + RSTART, RLENGTH, CHFM[i], DOTS[i], FMTS[i]
                                                                                                 TMP = substr (TMP, RSTART+RLENGTH)
                                                                                                 PTR += RSTART + RLENGTH - 1
                                                                                                 TYP[j-3,FIDX[i]]++
                                                                                                }
                                        }
                 for (j=1; j<=2; j++) printf "|%s|%s", TYP[j,1], TYP[j,2]
                 print ""
                 split ("", TYP)

Thanks RudiC. Adding new fields at the end will work too.
But, I am not getting desired output for below input -

Good grief! What a heck of a problem. We have a "race condidtion" of what pattern occurs first in the pattern file and what occurs first in the string. When found a pattern, and reduced the string, we need to start over with the first pattern again. I think I have found a solution; try and report back:
Code:
FNR == 1        {FILENR++
                }

FILENR <= 2     {CHFM = CHFM DL $1
                 RGEX[$1] = $2
                 DOTS[$1] = $3
                 FMTS[$1] = $4
                 FIDX[$1] = FILENR
                 DL = "|"
                 next
                }

                {printf "%s", $0
                 for (j=4; j<=5; j++)   {TMP = $j
                                         PTR = 0
                                         while (match (TMP, CHFM))      {MTCH = substr (TMP, RSTART, RLENGTH)
                                                                         printf "|%s|%s|%s|%s|%s", PTR + RSTART, RLENGTH, MTCH, DOTS[MTCH], FMTS[MTCH]

                                        }
                 for (j=1; j<=2; j++) printf "|%s|%s", TYP[j,1]+0, TYP[j,2]+0

FILENR <= 2     {CHFM = CHFM DL $1
                 RGEX[$1] = $2
                 DOTS[$1] = $3
                 FMTS[$1] = $4
                 FIDX[$1] = FILENR
                 DL = "|"
                 next
                }

                {printf "%s", $0
                 for (j=4; j<=5; j++)   {TMP = $j
                                         PTR = 0
                                         while (match (TMP, CHFM))      {MTCH = substr (TMP, RSTART, RLENGTH)
                                                                         printf "|%s|%s|%s|%s|%s", PTR + RSTART, RLENGTH, MTCH, DOTS[MTCH], FMTS[MTCH]
                                                                         TMP = substr (TMP, RSTART+RLENGTH)
