我想我已经解决了光栅中断 text/bitmap 模式，但我有这个奇怪的文本错误
I think I have solved raster interrupts text/bitmap mode but I have this weird text error
汇编程序：CBM prg Studio。
大家好，圣诞快乐，节日快乐:)
我的中断中的文本输出是怎么回事？我一定在这里遗漏了一些明显的东西，但请看一下所附的图片...
应该说：
“正在进入第一个候选人的范围...”
*位图显示
“开始开采 Y/N？”
看看附图，自己看看。
下面是代码。感谢您抽出时间来看一看，这让我困惑了一晚上！

这个问题似乎与 PETSCII specification 的功能有关，称为 shifting。
Assuming the graphics mode is unshifted, PETSCII has only uppercase letters in its powerup state.
在移位模式下，小写字符 a-z 与未移位模式下的大写字符 A-Z 占用相同的字符 space (0x41..0x5a)。在此模式下，大写字符位于 (0x61..0x7a)，其中包含未移位模式下的一些图形字形。
证据支持这一点，因为小写字母显示为大写字母，大写字母显示为块图形字符。
解决这个问题：
On C64 the sets are alternated by flipping bit 2 of the byte 53272
或者，我认为可以不使用 KERNAL 函数直接将正确的字符输出到屏幕内存。我不确定这一点，因为我编写 C64 已经很长时间了。可能是需要禁用字符集的切换，以便随机按键不会改变屏幕...
