What is the code for 0401 optimized?

There are restrictions. It can only convert up to 10 hexadecimal digits (excluding the first two 0s), but it seems to be sufficient.

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

:10to16
set/a q=%1
:1c
set/a r=%q%%%16
set/a q=%q%/16
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%%
if not %q% equ 0 goto :1c
call set r=%%r%1%%

:10to16
set H=0123456789ABCDEF
set/a q=%1
:1c
set/a r=%q%%%16
set/a q=%q%/16
call set r=%%H:~%r%,1%%
call set r%1=%r%%%r%1%%
if not %q% equ 0 goto :1c
call set r=%%r%1%%

Brother zh159 makes a valid point. I said something wrong again. Indeed, my code is a bit worse. I'll correct it!

Not VB library

It is VBA (Visual Basic for Applications) built into Office

vbe6.dll is a dll of the VB editor.

Actually, the easter egg in my signature is also in VB6, the same.

Hey, is it off-topic?
