Hello everyone:
How can the function of reading a property file or options file be implemented under DOS?

There are generally the following 3 ways to read options in DOS:
1. Set environment variables in advance, and reference the environment variables in commands
2. Use the built-in command-line parameter reading function of certain commands themselves
3. Read a specified config file / options file / property file, and extract variable values from it

The first two cases are relatively easy to handle, but how can case 3 be implemented?

I'm asking the experts, seniors, and friends in the DOS world for advice. Please share your opinions! Thanks!

Let me bump this first!

This function is very common in many situations, and I hope everyone can give some good solutions!

You can use INT 21H function 43H to get/set file attributes, and 57H to get/set file time attributes.

The contents of the BAT version of propImport.bat that I implemented are as follows:

@echo off&goto Start

20080525 cao
a prop reader implemented by bat file
commentChar is #
prop definition like propName=propValue

:Usage
echo Usage: %~n0 propFullPathName
goto End

:Start
set commentCahr=#
set delimChar==
if not "%~1"=="" (set propFile=%~1) else goto Usage

for /f "eol=%commentChar% tokens=1,* delims=%delimChar%" %%i in (%propFile%) do @set %%i=%%j

:End

Can you give an example of using 57H to get/set file time attributes?
