Passing Shell Variables to an awk command

Hello,

I have two files File1 & File2.

File1
76 135
136 200
250 345
....

File2
1 24
1 35
1 36
1 72
....

I want to get all the values form File2 corresponding to the range in File 1 and feed it to a program. Is the code below right? Can I pass shell variables to awk in this manner?

Code:
while read i,j
do
awk '$2>="$i" && $2 <="$j"' File_2 | my_code

done <File1

Thanks,
Guss.

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
