4: ; DESCRIPTION
5: ;
6: ; This is the header file used by assembly files to determine
7: ; model dependent information. Previously, Greenleaf libraries
8: ; used the file model.h, which had macros for _LCODE, _LDATA, etc.
9: ; This new system allows the user to set the model on the command
10: ; line by defining the GF_MODEL constant. It also prints out a
11: ; helpful (I hope) error message if GF_MODEL is not defined.
12: ;
13: ; This file also has segment definitions for the code used by
14: ; the 286 DOS Extender Fast drivers. If you were to mess with
15: ; those segment definitions, the results would probably be
16: ; very bad.
