The handle is checked instead of changing vectors, and *SPOOL/*EXEC without a filename close any currently open SPOOL/EXEC file. DiskNotReady from floppies is ignored, allowing easier use of 3.5" floppy drives. With a teletext display characters &23, &5F, &60 (# _ `) need to be stored in screen memory as &5F, &60, &23. The SPOOL/EXEC update releases enough space to allow teletext character conversion on OSWRCH and OSRDCH in SYSDOS40. The startup display is 'Acorn DOS' in capitals as a visual reminder. On startup, if there is code at &A000 that starts with a JSR (a &20 byte) it is entered at &A000.
