; asm.h - all asm*.s TC/MC/Aztec assembly include file
;
; 7/26/92 v6.3 TSC support
; 11/17/92 original version
;
; #define __LARGE__, __MEDIUM__, __SMALL__ for model
; #define AZTEC, TURBOC, or MSC for C Compiler
;
; Routines included:
;
;       include asm.h   - start the assembly file
;       .header         - create the code and data segs
;       .cseg           - start the code segment

;       .dend           - end the data segment
;       .dsym name,type - declare global C data (type=word,byte)
;       .cextp name     - reference an external C procedure, use model as type
;       .cextrn name,type- reference external C variable and type(word,byte)

;       .cendp name     - end C procedure
;       .center         - enter C procedure (set up BP etc)
