Although not advertised on the Bris site any longer the Windows 3.1 and the Windows 95 version of A-Odds Silver is still available for download. This uses the "HAT" file and enables you to save to EXDC format and other Sartin Programs as well.
It has an option to save in the old 3 call and 4 call format. This may serve your purposes.
