; 		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.
