China DOS Union

Below is a program for converting strings in table order. The original text comes from the development room of this site:
http://model.chinajewelry.net/dos/dosbbs/dispbbs.asp?boardID=6&ID=9250

This program is written for the sequential conversion of string values in batch processing. It is generally called as a subroutine by other programs. It can also be slightly modified and added as a sub-module call in a specific batch processing program.

@echo off
if == goto %2
if == goto nullargu

:main Main module: The parameter lists of count and match can be reset and increased or decreased as needed
set factor=%1
call %0 $ count 1 2 3 4 5 7 8 9
call %0 $ match c d e f g h i j
goto display

:count Counting module: Set variable values #a1, #a2 according to the specified parameter factor
if == goto overflow
set #a1=%#a1%-
if not == goto count_2
set #a1=
set #a2=%#a2%+
if == goto overflow
:count_2
if == goto end
shift
goto count

:match Matching module: Loop to increment variables #b1, #b2. If they are equal to #a1, #a2 respectively, then specify the result value as the current loop parameter 3.
if == goto overflow
set #b1=%#b1%-
if not == goto match_2
set #b1=
set #b2=%#b2%+
if == goto overflow
:match_2
if == if == set result=%3
if not == goto end
shift
goto match

:display Display module: Display the assignment result
if == echo %factor% convert %result%
set result=
set factor=
set error=
set #a1=
set #a2=
set #b1=
set #b2=
goto end

:nullargu
echo.
echo Error: argument 1 not specified.
echo.
goto end

verflow
echo.
echo Error: number is overflow.
set error=overflow
echo.
goto end

:end

Here is the translation:

The following is a program to get the errorlevel value into an environment variable. The original text comes from the development room of this site:
http://model.chinajewelry.net/dos/dosbbs/dispbbs.asp?boardID=6&ID=9358

@echo off
set el=0
if errorlevel 1 set el=1
if not errorlevel 2 goto end

:partbydec
for %%h in (1 2) do if errorlevel %%h00 set elh=%%h
if == for %%t in (0 1 2 3 4 5 6 7 8 9) do if errorlevel %elh%%%t0 set elt=%elh%%%t
if == for %%t in (0 1 2 3 4 5) do if errorlevel %elh%%%t0 set elt=%elh%%%t
if not == for %%o in (0 1 2 3 4 5 6 7 8 9) do if errorlevel %elt%%%o set el=%elt%%%o
if == for %%o in (0 1 2 3 4 5) do if errorlevel %elt%%%o set el=%elt%%%o
set elh=
set elt=

:end
if not == echo current errolevel is %el%

Good
A very classic batch script

The LZ really has a special liking for batch processing. I'll take it first and read it slowly. (Can't help but reply first, and strive to gain something in a few days)

Originally I once planned to make a batch processing that traverses directories, but didn't write it out. Later I used C to write, but the result is also very clumsy - some directories will crash. It's best to complete this kind of thing with DOS itself.

I still don't know how to use

The following is the statement from zww3008 on 2004-1-14 15:42:25:
These are all very classic batch processing programs, which are very worthy for beginners to learn, refer to and experience. If you don't want the post to be watered down, then please ask the moderator to pin it! Don't let the post sink.

Finally found it again
I'm really lucky~~
For everyone
I'll give it a top

Depressed, why do I feel that the more I learn, the more things I don't understand? I just wanted to play for a few more days at the beginning of school. I'll go to the library tomorrow.

It is indeed a rare and good teaching material, and I'll bring it back to the top again!

```
Top top top
```

O.O Such a classic thing, extremely powerful!

Can't help but top it again, miss willsort

Yeah, it's been a long time since I saw Brother willsort's wonderful "lecture", miss it...

How can such a wonderful post be allowed to sink ～:)
Appreciation ～:)

Nice
