RudiC,
Note that High-T did get an infraction for using URGENT and double-posting in another thread. I decided that one infraction was required, but didn't think two infractions were necessary at this time.

I also believe that High-T needs to look more closely at the working code he has been given and the new requirements presented in this thread and take a little time to THINK about what different needs to be done to satisfy those new requirements.

High-T,
In the 5 days since you joined this forum, you have submitted 6 threads all based on a very similar awk script. After fixing your code four times to do your tasks, you have submitted two more threads for this problem and say that we volunteers need to URGENTLY fix your code even though it looks like you are not willing to apply suggestions we have suggested in the four threads we solved for you. We are volunteers; not your paid programming staff. You have no right to expect volunteers here who have helped you with other problems (or new volunteers who may be willing to help you) to put aside other things they might have planned to do this weekend to help you meet your deadlines.

Please show us what in your current code is intended to move any lines out of File1.txt.

Please tell us what the code:

Code:

    $1=="01" &&
                FNR>1       {keyfound?"77\t" keyfound:"99"}

is intended to do. It is a nice expression, but it produces no output and sets no variables.

Given that you never use the variable lines except in these two statements:

Code:

        lines = ""
           and
    lines = lines $0 "\n"

please tell us what this variable is intended to do. Are you trying to use this to save up lines to be printed when you get the end of a set if a match was found? That would make sense; but that isn't what you're doing. Are you trying to save up lines to be reprocessed on a later run if no match is found? That would make sense, but that isn't what you're doing.

Given that File2.txt has leading spaces and that the length of the 1st field in that file is variable length (not a constant 14 characters), it would seem that:

Code:

    		a[substr($0,1,14)]=$0

might need to be something more like:

Code:

    		a[$1]=$0

The key used in your other threads could be set when you found a record starting with 01. In this thread you can't set the key until you have found both a 01 record and a 07 record. And, you can have more than one key for a single set of records. Therefore, you need to accumulate an entire set of records that may need to be printed until you have found the entire set of keys for that set and have determined whether there are any matching keys. If you look closely at your output, you will note that you haven't printed lines out of order; instead, you have printed lines starting from when you finished a matching key when you found a record starting with 07 and continued printing lines until you find another 07 record that doesn't match. BUT, I can't see how you would get the output you showed us with the code you've shown us?????

Hopefully, these comments will help you produce a working script.
