 Antonio,

Do you have control over the contents (format) of the data?
Here that would be "Soccer.dat".

If yes I'd suggest a format change.  Separate the goals with
dashes (-) or commas (,) or whatever, just no something that
makes you think of them as numbers but as strings to be
converted to numbers later.

Assuming you used dashes teams 2 and 8 would be:

    Team2 1 1-2
    Team8 2-0-1 2-0-3

Your code could then use split(...) to put the goal counts into
an array.  For example.

    split($2, GF, "-")
    split($3, GA, "-")

You would now have two arrays GF (Goals For) with up to 3 elements.
The first would be regulation, second overtime, third penalty kicks.
And of course the same for GA.

This would also eliminate a potential, but very rare problem,
Some team scores 10 goals in overtime.  Your scheme would make
it look like 1 goal and 0 penalty kicks.

Dear Sir,
I do have control of the data.  I just wanted to have a solution running from a shell
script.  I have an opendocument(*.odt) and excel spreadsheet that uses the decimal point
and converts the decimal numbers to goals except in the hundredths place which is when we
have to shoot penalty kicks(PK) to decide the game, but this is for my fellow coaches,
they have to manually input the scores and put a * at the score indicating OT, PKS etc. 
Some may not understand it :(  
My questing regarding the data is that in one case, I had in Team2Team2 1.0 1.2  which
should give 1 3 but it output 1 2 :(I had to change to 0.1 and 0.3 and it correctly put
the goals at 1 3 and awarded 1 pt for going into OT.  

How do I fix the script to account for the new changes/examples?  At the end of the
running the script should tally up the GF  and GA except in PKS those do not count in the
DIF.  So my soccer.dat would become as follows:
Soccer.dat-------------------------------
@Team1 1 2Team2 1-0 1-2Team3 2 4Team4 3 0@Team5 4 0Team1 3 1@Team2 1 3@Team3 4 3@Team4 3-0
3-1Team5 3 0
At the end of each line, the GF and GA will be adjusted and at the very end of the data,
the script should report a running total of all GF and all GA and the PTS.  
Thank you very much for your help!

Best Regards,

Antonio
