Ok! You convince me to use awk. At least to try! Let?s see if somebody could help me, please:

I have the following files: (MSC.080806.00, MSC.080806.01, MSC.080806.02...) each one has the same pattern, with two different START and STOP times and values:

...
START:2008/08/06 08:30:00 WED; STOP: 2008/08/06 09:00:00 WED;
...
TRK
KEY (COMMON_LANGUAGE_NAME)
INFO (OM2TRKINFO)
INCATOT PRERTEAB INFAIL NATTMPT NOVFLATB GLARE
OUTFAIL DEFLDCA DREU PREU TRU SBU
MBU OUTMTCHF CONNECT TANDEM AOF ANF

Using another very valuable hint from you, I could separate the lines with START and STOP patterns to record them into MySQL after some cuts:

edu@ubuntu:~/routes# awk '/START/{ print; }' MSC.080806.20
START:2008/08/06 08:30:00 WED; STOP: 2008/08/06 09:00:00 WED;
START:2008/08/06 09:00:00 WED; STOP: 2008/08/06 09:30:00 WED;

And then, I separated the lines to save as columns names for my MySQL fields :

edu@ubuntu:~/routes# awk '/OM2TRKINFO/{ getline; print; }' MSC.080806.20
INCATOT PRERTEAB INFAIL NATTMPT NOVFLATB GLARE
INCATOT PRERTEAB INFAIL NATTMPT NOVFLATB GLARE

But, I have more 3 lines to do that:
edu@ubuntu:~/routes# awk '/OM2TRKINFO/{ getline; getline; print; }' MSC.080806.20
OUTFAIL DEFLDCA DREU PREU TRU SBU
OUTFAIL DEFLDCA DREU PREU TRU SBU

MBU OUTMTCHF CONNECT TANDEM AOF ANF

I don?t think this getline; ...; getline way is the better way!!! It doesn?t look elegant or professional. So how could I do that in awk avoiding many getlines?

But the worst problem is how to get the fields values:

The file has:
75 RJOTLP1_TLMARC
2W 709 709
3101 0 0 5095 0 0
4 0 0 0 5172 0
0 0 5091 1582 0 0
5172 4775 4025 0 0 0

As an example, I need: values(FIELDS)

RJOTLP1_TLMARC (TRK)

3101 (INCATOT) 0 (PRERTEAB) 0 (INFAIL) 5095 (NATTMPT) 0 (NOVFLATB) 0 (GLARE)
And so on:
4 0 0 0 5172 0
0 0 5091 1582 0 0
5172 4775 4025 0 0 0

I mean: TRK=RJOTLP1_TLMARC, INCATOT=3101, and so on.

Thank you and best regards. Sorry about the long post.
