i wanna get a column getting ( DataField under ID : 515 ) in the variable part that its not in same place every time and variable fields are not of a fixed number and if he couldnt find ID 515 return with ( not found )

to make output
Code:
Paris 
london 
cairo 
not found   ....... as Id 515 not found

agama wrote me this
Code:
nawk -v target={$1, -515} '
    BEGIN {
        value["DataField"] = "Not Found";
    }

    /Variable #/  { snarf = 1; next; }

    snarf > 0 && $1 == "End" {
        snarf = 0;

        if( value["DataId"] == target )
            printf( "%s\n", value["DataField"] );

        split( "", value, "." );
        value["DataField"] = "Not Found";
        next;
    }

    snarf > 0 && $(2) == ":" {
        value[$1] = $3;
    }
'

The input to the awk programme is the file containing the 'data' that you posted in the first part of the thread. If it is in a file named "list" then executing the command with <list as the redirection the output should be as you desire.

Thanks
In my reply I've write to you there wasn't output
Code:
bash# ./ List.ksh 300 <list >list1
bash# cat list1

List : source of data
List1: output saved in it but it's empty 

Please look at my last reply to you :D

Some slight changes should get it working for you:

Code:
nawk -v target=${1:-515} '
    $1 == "End" && $2 == "of" {
        if( value["Id"] == target )
            print value["DataField"];
        else print "Not Found";
        split( "", value, "." );
    }
    $1 == "End" {snarf=0; next }
    $1 == "Id" && $3 == target { snarf=1 }
    snarf && $2 == ":" {value[$1] = $3}
' infile

That is just to clear the 'value' array as you awk dosn't support delete value. It's splitting the blank string with a seperator of "." and putting the blank result into the 'value' array.
