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)
; NV_FEATURE_PARAMETER 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)
; NVPowerModeEnabled : WORD (+0, 2byte)  wpoke st,0,値  /  値 = wpeek(st,0)
; NVParameterReserv1 : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; NVCmdEnabled : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; NVParameterReserv2 : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; NVPowerModeVer : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; NVCmdVer : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)
; NVSize : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; NVReadSpeed : WORD (+16, 2byte)  wpoke st,16,値  /  値 = wpeek(st,16)
; NVWrtSpeed : WORD (+18, 2byte)  wpoke st,18,値  /  値 = wpeek(st,18)
; DeviceSpinUpTime : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; ※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。
