Oh my bad. I didn't notice you are running program in a file!

Edit your file: script.awk put only code fragment:
Code:
!/^[ \t]+Abs/ && !/^[ \t]+B-1/

To run your program:
Code:
awk -f script.awk your_input_file

Follow the same for other code fragment in script.awk:
Code:
$0 ~ /^[ \t]+Abs.*/  {
                next
} $0 !~ /^[ \t]+B-1.*/ {
                p = (p=="")?RS $0:p RS $0
} $0 ~ /^[ \t]+B-1.*/ {
                sub(/,$/,"}",p)
                print p
                p = ""
}

To run your program:
Code:
awk -f script.awk your_input_file

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       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)
		 ...
