Simple awk search problem

Hello;

we have :

Code:
awk '/reg_exp/,0/

prints every line after the first occurrence of "reg_exp"

But if I want to print rest of the lines AFTER the last occurrence of "reg_exp",
how would I do it ??

Tried :

Code:
awk ' ! (/reg_exp/,0)'

But it errored...

Thank you for any suggestions..

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
