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)
; MEASURED_LATENCY サイズ: 24 バイト(x64)
dim st, 6    ; 4byte整数×6(構造体サイズ 24 / 4 切り上げ)
; Trim3 : WORD (+0, 2byte)  wpoke st,0,値  /  値 = wpeek(st,0)
; Write3 : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; Read3 : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; Trim2 : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; Write2 : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; Read2 : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)
; Trim1 : WORD (+12, 2byte)  wpoke st,12,値  /  値 = wpeek(st,12)
; Write1 : WORD (+14, 2byte)  wpoke st,14,値  /  値 = wpeek(st,14)
; Read1 : WORD (+16, 2byte)  wpoke st,16,値  /  値 = wpeek(st,16)
; Trim0 : WORD (+18, 2byte)  wpoke st,18,値  /  値 = wpeek(st,18)
; Write0 : WORD (+20, 2byte)  wpoke st,20,値  /  値 = wpeek(st,20)
; Read0 : WORD (+22, 2byte)  wpoke st,22,値  /  値 = wpeek(st,22)
; ※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。
