; 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.
