zh159兄，你的转换多位的代码与我的代码相比也不见得不啰嗦啊~~~~~~~~
不好意思，我收回这句话。
其实各有优缺点。
你的简单但降低了代码可读性而且加大了“程序处理量”（0-9都替换了），我的啰嗦但提高了代码可读性。
在“程序处理量”方面，你的处理量应该更大：
call set r=%%r:10=A%%
call set r=%%r:11=B%%
call set r=%%r:12=C%%
call set r=%%r:13=D%%
call set r=%%r:14=E%%
call set r=%%r:15=F%%
call set r%1=%r%%%r%1%%
这部分也是一个替换过程，每次转换都要历经六次替换，0-9的数据也会一样处理，只不过0-9里面没有“10-15”数字，不会替换出A-F；
我那个简化的（原出处应该是不得不爱版主）虽然降低了代码可读性，但只要一次过替换（实际上是字符截取），效率高些
其实只要对比一下就可以发现相同的地方

call set r=%%r:14=E%%
call set r=%%r:15=F%%
call set r%1=%r%%%r%1%%

call set r=%%r%1%%

Brother zh159, your code for converting multiple digits is no less wordy than mine~~~~~~~~
I'm sorry, I take that back.
Actually, each has its own advantages and disadvantages.
Yours is simple but reduces code readability and increases "program processing volume" (replaces 0-9 all). Mine is wordy but improves code readability.
In terms of "program processing volume", your processing volume should be larger:
call set r=%%r:10=A%%
call set r=%%r:11=B%%
call set r=%%r:12=C%%
call set r=%%r:13=D%%
call set r=%%r:14=E%%
call set r=%%r:15=F%%
call set r%1=%r%%%r%1%%
This part is also a replacement process. Each conversion has to go through six replacements. Data from 0-9 is also processed the same way. It's just that there are no "10-15" numbers in 0-9, so A-F won't be replaced out;
The simplified one I have (the original source should be the version of the moderator Budu Bu Ai) although it reduces code readability, but only needs one-time replacement (actually character interception), which is more efficient
In fact, you can find the same place by just comparing

call set r=%%r:14=E%%
call set r=%%r:15=F%%
