HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; IMAGE_SEPARATE_DEBUG_HEADER サイズ: 48 バイト(x64)
dim st, 12    ; 4byte整数×12(構造体サイズ 48 / 4 切り上げ)

; Flags : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; Machine : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; Characteristics : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; TimeDateStamp : DWORD (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)

; SectionAlignment : DWORD (+36, 4byte)  st.9 = 値  /  値 = st.9   (lpoke/lpeek も可)
; Reserved : DWORD (+40, 8byte)  varptr(st)+40 を基点に操作(8byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
