; ----       ----       -----------
; 07-Feb-94  TMD        Created file
; 20-Jul-94  AMcC       Made compatible with Hdr file changes:
;                       - GETs Hdr:PublicWS rather than defining SoundWorkSpace.
;                       - Hdr:File has been split into Hdr:FSNumbers and Hdr:HighFSI
;                         GETs Hdr:FSNumbers (needed by NewErrors) (was GET Hdr:File).
;                       - FilerAction hdr file is now called FilerAct (was Filer).
;                       - Filter hdr file is now called Filter (was Filters).
;                       - Squash hdr file is now called Squash (was Compress).
;                       - Removed GET  Hdr:DBox
;                       - Removed GET  Hdr:ROMCache
; 22-Sep-94  AMcC       #ifdef __cplusplus lines included in derived file (from IJohnson)
; 22-Sep-94  AMcC       Generates SWI name defs for all SWIs listed in PRM (3.50 version)
; 12-Oct-94  AMcC       Added SWIs for DDT (HLLDebugger) and HostFS (Tube)
; 03-Jan-95  AMcC       Added CDROM and SCSI SWIs (as requested by SPalmer)
; 09-Jan-95  AMcC       Added #defines for INR(..) and OUTR(..)
;                       Added usage comment (for Aquarius Toolbox)
;                       Updated version and date for header of output file
;

; AAsm source file to make h.swis file from Hdr:SWIs and other headers
