Environment Variables in Windows 95

Keywords: environment variable 

---

Problem:

I'm using WinBatch under Win95 to run a DOS app that sets an environment variable. Later in the WinBatch program I want WinBatch to be able to reference this environment variable but it's not getting set. If I run the DOS app from DOS, it does set the environment variable, but it seems that WinBatch is not allowing that to happen.

Answer:

Windows is not allowing it to happen. The DOS app can only set environment variables for itself. Not for any other program.

There is a Microsoft utility that can be used to set a global DOS variable in Windows 95. The utility is called "WinSet" and it's in a self-extracting archive file named "envars.exe". It's used almost identically to the DOS Set command, except it changes the master DOS environment in Windows 95.

What are you trying to do? If you are trying to return an errorlevel to WinBatch, see ERRORLEVEL.* in the samples subdirectory.

Are you trying to return other info to WinBatch? To write info to a ini file like thusly...

  
      echo [MyData] > c:\temp\mydata.ini
      echo envvar=%envvar% >> c:\temp\mydata.ini

In WinBatch, do the following:

      envvar=IniReadPvt("MyData","envvar",0,"c:\temp\mydata.ini")
