Regex escape special character in AWK if statement
I am having issues escaping special characters in my AWK script as follows:

Code:
for id in `cat file`
do
grep $id in file2 | awk '\
    BEGIN {var=""} \
    { if ( /stringwith+'|'+'50'chars/ ) {
        echo "do this"
    } else if ( /anotherString/ ) {
        echo "do that"
    } else {
        echo "do other"
    } }'
done

I am not sure how I am supposed to escape the multitude of characters in the regex string "stringwith+'|'+'50'chars"

SYNOPSIS

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

       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
