Re: Q&A: MSDOS SET command gave me some of my mapped commands

No - I do not want to get rid of the commands. They are a part of my VIM Script when I edit a PHP file. After trying several things for a few hours all I can say is - is that for some reason, when I execute the PHP - these three commands just include themselves. Unknow why. Oh well, I'll just make sure to remove them from whatever information I get from doing an EXEC() command. I was mainly wondering if VIM makes temporary Windows variables.

So it seems you did define those in your environment, not inside vim.
Check Environment settings for your Windows operating system.

What exactly did you try? You should either use `:unlet $map_h` but this
will only unset those variables inside your Vim session, or using
set map_h=
in a cmd.com terminal window to remove it temporarily inside your
cmd.exe session.


Thanks,
