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)
; GNSS_BREADCRUMB_V1 サイズ: 40 バイト(x64)
dim st, 10    ; 4byte整数×10(構造体サイズ 40 / 4 切り上げ)
; FixTimeStamp : FILETIME (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; Latitude : DOUBLE (+8, 8byte)  qpoke st,8,値 / qpeek(st,8)  ※IronHSPのみ。3.7/3.8は lpoke st,8,下位 : lpoke st,12,上位
; Longitude : DOUBLE (+16, 8byte)  qpoke st,16,値 / qpeek(st,16)  ※IronHSPのみ。3.7/3.8は lpoke st,16,下位 : lpoke st,20,上位
; HorizontalAccuracy : DWORD (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; Speed : WORD (+28, 2byte)  wpoke st,28,値  /  値 = wpeek(st,28)
; SpeedAccuracy : WORD (+30, 2byte)  wpoke st,30,値  /  値 = wpeek(st,30)
; Altitude : SHORT (+32, 2byte)  wpoke st,32,値  /  値 = wpeek(st,32)
; AltitudeAccuracy : WORD (+34, 2byte)  wpoke st,34,値  /  値 = wpeek(st,34)
; Heading : SHORT (+36, 2byte)  wpoke st,36,値  /  値 = wpeek(st,36)
; HeadingAccuracy : BYTE (+38, 1byte)  poke st,38,値  /  値 = peek(st,38)
; FixSuccess : BYTE (+39, 1byte)  poke st,39,値  /  値 = peek(st,39)
; ※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。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
