Restore master.lib's FUNC and ENDFUNC macros With seg000 changed to word alignment and all definitions for "func" removed, the master.lib functions can keep their exact alignment themselves. [Binary change] db 0 → nop before get_machine_98() in the MAIN.EXE and MAINE.EXE files of TH04 and TH05, respectively.

; *Not* the original file. The memory model conditional branches at the
; beginning had to be rewritten to refer to TASM's @MODEL symbol instead.
[Reduction] #30: get_machine_at Um. Not sure if ZUN used an older version there, or if these additional branches simply resulted from a lack of optimization... And I even had to convert the labels to local syntax.

; Description
; NEAR版とFAR版をアセンブル時に選択設定するためのincludeファイル
;
; Usage:
; include時に NEARMODEL が定義されていると near版を生成し、
; 定義されていなければ FAR版(Pascal版と共用)を生成する。
; さらに、COMPACTMODEL, MEDIUMMODELも使える。
; 　アセンブルオプション/Dを使用するとソースの変更なしに両方の
; 生成ができる。

[JWasm move] Don't use the DIST/CALLMODEL constants for procedures and labels Once you've actually found the right syntax that makes the assembler just use the default call type of the current memory model for both procedures (where it's just "PROC" without anything else) and labels (where it's "LABEL PROC"), these constants become completely unneccessary, even with TASM.
