;
; Interrupt 2Eh Call
;
; From information originally published in
; PC magazine, April 28, 1987. Requires
; MASM 5.1 or later.
;
; Adapted by Bob Stout.
;
; NOTES: INT 2Eh passes a formatted command line
; directly to the resident portion of
; COMMAND.COM for execution. It functions
; similarly to the 'EXEC' function in DOS
; but is generally quicker. This is an
; undocumented DOS function and is subject
; to change in future releases of DOS. It
; also aborts any .BAT file which invokes
; a program which uses it. Use with care!
;
; Assemble with: MASM /Mx /z ...
; TASM /jMASM /mx /z ...
;
% .MODEL memodel,C ;Add model support via
;command line macros, e.g.
;MASM /Mx /Dmemodel=LARGE
