awk,gawk in bat file

Hi.
I'm trying to convert bat file into shell script. Bat file invokes awk file in one section:
c:\upg\exe\gawk -f c:\upg\awk\gen_sae.awk -v OP=C:\\upg\\lod\\... ...c:\upg\ref\saaxi.ref c:\upg\log\SAAEPWO.log c:\upg\ref\saaepref.log

First of all I issued unix2dos command on that awk file. After that I got an error in this line:
if ( match( $0, /FORCE{/ ) ) {

Can someone please explain what is wrong with that line? When I run bat file in DOS it doesn't complain.
