; Real procedure entry points.
;
; REALSCHM.ASM is a real procedure which is loaded upon initialization of
; Scheme and accessed via real procedure calls. It currently contains a
; table of 25 entries (0-24) which contain routines accessable from our
; protected mode code. The first 20 entries will contain addresses to
; code within realschm.asm, primarily for things like xli support which
; can't be provided in protected mode. The next 5 entries are for system
; xli routines. An xli routine is distinguished as a system xli routine by
; having the FB_SYSINT flag in the file block set non-zero. Note that the
; system xli routines must be in a specified order, as defined in
; PRO2REAL.ASM.
