' 21 点（BLACKJACK）—— 用 **BASIC** 写的手机游戏
' Blackjack -- a mobile game written in **BASIC**
'
' 出处与版权：原型是 1970 年代流传最广的那份 21 点 BASIC 程序（收进 David Ahl 的
' Origin and copyright: the prototype is the most widely circulated blackjack BASIC
' 《BASIC Computer Games》，原版叫 BLACKJACK 或 21）。**这份是照玩法规则重写的**：
' program of the 1970s (collected in David Ahl's "BASIC Computer Games"; the original was called BLACKJACK or 21).
' 结构、变量名、注释、绘制方式都是自己的，没有抄原件的一行代码 ——
' **This one is rewritten from the rules of play**: the structure, variable names, comments and drawing
' 与 `gorilla.bas` 同一条规矩（`Examples/` 会随 APK 分发）。
' are all our own -- not one line copied from the original, the same rule as `gorilla.bas` (`Examples/` ships with the APK).
'
' 玩法：标准赌场规则简化版 —— 庄家 17 点停（软 17 也停）、A 可当 1 或 11、
' Play: a simplified version of standard casino rules -- the dealer stands on 17 (soft 17 too), an ace counts 1 or 11,
' 天生 21 点（两张就 21）赔 3:2、其余赢赔 1:1、和局退还赌注。筹码有限，输光就结束。
' a natural 21 (two cards) pays 3:2, other wins pay 1:1 and a push returns the bet. Chips are finite; losing them all ends the game.
'
' ◆ 手机上怎么玩
' ◆ How to play it on a phone
'
' 原版是打字问「要不要牌（H/S）」，这里改成**三个大按钮**：要牌 / 停牌 / 加倍。
' The original asked you to type whether to take a card (H/S); here it is **three big buttons**: Hit / Stand / Double.
' 赌注用 −/+ 调（下注阶段），发牌后按钮换成要牌/停牌/加倍。
' The bet is adjusted with -/+ during the betting phase, and after the deal the buttons become Hit/Stand/Double.
' —— 回合制游戏在手机上就该这么处理：**别让玩家调键盘**。
' -- that is how a turn-based game should be handled on a phone: **never make the player work a keyboard**.
'
' ◆ 写法提醒（这几条是本前端**当前**的硬约束，都不是"建议"）
' ◆ Writing notes (these are **current** hard constraints of this frontend, not "suggestions")
'
' · **数组维度必须写字面量**：`DIM a(N) AS INTEGER`（N 是 CONST）**不生效** ——
' · **Array dimensions must be written as literals**: `DIM a(N) AS INTEGER` (N being a CONST) **does not take effect** --
' 实测 `a(4)` 恒为 0，而 `DIM a(5)` 正常（见 FRONTEND_DEFECTS.md 的 BASIC 一节）。
' measured: `a(4)` is always 0, while `DIM a(5)` works (see the BASIC section of FRONTEND_DEFECTS.md).
' · **有返回值的必须写 `FUNCTION`**（`SUB … AS INTEGER` 会去链一个 `func_integer`），
' · **Anything with a return value must be written as `FUNCTION`** (`SUB ... AS INTEGER` goes off and links a `func_integer`),
' 且收尾必须是 `END FUNCTION`（写成 `END SUB` 会让整个解析错位）。
' and it must end with `END FUNCTION` (writing `END SUB` derails the whole parse).
' · ~~**不要写无参 `FUNCTION`**（它恒返回 0）~~ —— ✅ **2026-10-04 复验已修好**：
' · ~~**Do not write a parameterless `FUNCTION`** (it always returned 0)~~ — ✅ **re-checked fixed on 2026-10-04**:
' 实测 `FUNCTION roll() / roll = 7 / END FUNCTION` 打出 `7`。
' measured: `FUNCTION roll() / roll = 7 / END FUNCTION` prints `7`.
' · 外部过程写 `NATIVE SUB` / `NATIVE FUNCTION` + 空体（这份照旧这么写）。⚠ 当年是**必须**的、
' · External procedures are written `NATIVE SUB` / `NATIVE FUNCTION` plus an empty body (this file still writes it that way). ⚠ Back then it was **required**
' **2026-10-04 复验已不必**（链接期会认领库侧符号，实测不写 `NATIVE` 照样拿到真值 480）。
' and **re-checked 2026-10-04: no longer needed** (the linker claims the library-side symbol; measured: without `NATIVE` it still returns the real value 480).
' · 颜色写 `&HFFrrggbb`。
' · Colors are written as `&HFFrrggbb`.
' ── UI 接口：引用**库侧**的声明文件（原先这里是一屏 NATIVE 声明）────────────────
' ── UI interface: include the **library-side** declaration file (this used to be a screenful of NATIVE declarations)
'$INCLUDE: 'vml_ui.bas'
' 音效：**用 `ui_audio_beep` 单音**（v0.96.509 统一换回来）。
' Sound: **use the single-tone `ui_audio_beep`** (switched back uniformly in v0.96.509).
' ⚠⚠ 一度走共享库的音序器（`ui_sfx_add`），**真机上破音**（多个音叠着响 + 长音拖尾）
' ⚠⚠ It once went through the shared library's sequencer (`ui_sfx_add`), which **clips on real devices**
' ⇒ 全换回单音的 beep：它是**单通道**的（后一个音掐掉前一个），结构上不可能削波。
' (several tones ringing on top of each other plus a long tail) => everything switched back to single-tone beeps:
' ⚠ 频率取原音型的**首音**；**胜负取两端的极值**（赢取最高音、输取最低音 ——
' a beep is **single-channel** (the next tone cuts off the previous one), so clipping is structurally impossible.
' 「不看屏幕也分得出」就靠这个，五子棋/象棋两版也是这么配的：赢 1320 / 输 240）。
' ⚠ The frequency is the **first note** of the original pattern; **win/lose takes the extremes of both ends** (highest tone for a win,
' 低音不低于 C3(131Hz)（手机外放 200Hz 以下衰减很快，听着像没响）。
' lowest for a loss -- "you can tell without looking at the screen" rests on exactly this; gomoku and chess are scored the same way: win 1320 / lose 240). Keep the low tone at or above C3 (131Hz), since a phone speaker rolls off fast below 200Hz and it sounds like nothing was played.
' ⚠ `ui_sfx_panic` 留着 —— 它是"全停"，退出前调一次把所有正在响的声音一起掐掉。
' ⚠ `ui_sfx_panic` is kept -- it is the "stop everything" call; run it once before exiting to cut off every ringing sound at the same time.
' ⚠ 形参名不能叫 on —— BASIC 关键字，会把 NATIVE 声明弄坏（当年实测；**2026-10-04 复验已修好**：
' ⚠ A parameter must not be named on -- it is a BASIC keyword and will break the NATIVE declaration (measured back then; **re-checked fixed on 2026-10-04**:
' 实测 `NATIVE SUB ui_grid_set(i AS INTEGER, on AS INTEGER)` 声明与调用都对）。这份**照旧**避开它。
' measured: `NATIVE SUB ui_grid_set(i AS INTEGER, on AS INTEGER)` declares and calls correctly). This file **still** avoids it.

' 报 `未定义的函数 'func_a'`）；✅ **2026-10-04 复验已可用**：形参写 `a(12) AS INTEGER`（或 `BYREF b() AS ANY`）、
' and went off to link it, reporting undefined function func_a); ✅ **re-checked 2026-10-04: they work now**: declare the parameter as `a(12) AS INTEGER` (or `BYREF b() AS ANY`)
' **实参必须带括号写 `arr()`** —— 实测 `f(t())` 读回 9，而写成 `f(t)` 会**静默**传进一个标量、读回 0。
' and **pass the argument as `arr()`** — measured: `f(t())` reads back 9, while `f(t)` **silently** passes a scalar and reads back 0.
' 这里**照旧**用偏移区分（能跑就别动），它同时也避开了"把算点数这条规则写两份"。
