;
;Purpose:
; Windows stream I/O data tables.
;
; The _iob[] and _iob2[] tables are each in their own segments
; so that additions can appended on easily and predictably (e.g.,
; windows). Also, note that _lastiob is also defined in its own
; segment so it always points to the last _iob[] entry regardless
; of what is added to the table.
;
; The data defined in this file is inserted in the _iob/_iob2 tables
; and, thus, those tables MUST be in the EXE.
