Question Variable syntax and lines of code

I am trying to use use the AWK and EGREP commands together in an AWK script. My overall objective is to count lines of code but exclude comments and blank lines and such.

I am able to use AWK with the FIND command like so:

Code:
| awk '{print \"wc -l \"$1}' > lineCount.sh

Now when I modify the line to use EGREP, I get a 'Variable Syntax' error

Code:
"| awk '{print \"egrep -cv '^$|^[*]|^[ *]|^[//]|^#|[\\n]'  \"$1}' > lineCount.sh

Regular expressions are new to me and they seem to be a bit painful. Any help is appreciated.

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
