Perhaps the following snippet will be of some assistance:
Code:
/PRIMARY +INDEX/ {
    s = $0
    while (!match(s, /PRIMARY +INDEX[^(]*\([^)]*\)/)) {
        getline t
        s = s t
    }
    $0 = s
    sub(/.*PRIMARY +INDEX[^(]*\([ \t\n]*/, "", s)
    sub(/[ \t\n]*\).*, "", s)
    print "ACCOUNT ID: " s
}

When it finds a line that contains the word PRIMARY followed by space(s) and the word INDEX, it will append lines (if necessary) until a parenthesized expression is found. The contents of that parenthetical, minus leading and trailing whitespace (space/tab/newline), are extracted.

Regards,
Alister

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
