Alan, Personally, I suggest abandoning SWAPGEN and just formatting/reserving the MDISK via CMS, then doing a mkswap /dev/disk/by-path/ccw-0.0.0xxx-part1 in your boot.local (or equivalent). This assumes that you are consistent in your assignment of the swap disk address. Then you don't have to worry about keeping some external routine up to date with changes in swap handling within a Linux guest.
Religious arguments....start your engines!
