If the IRS is newline, you cannot use gsub to strip the newline because
it
is not there, that is, $0 does not contain a newline. If ORS is newline,
then the newlines are added by print. Use printf to control when
newlines are
added, as in

/A:/,/B:/ { if( $0 ~ /B:/ ) printf( "\n%s\n", $0 );
            else printf( "%s ", $0 );
            next;

{ print; # this prints the lines that do not match above }

Hope that helps.
