       The reason? The space before the equals. SET FOO = BAR actually sets the environment variable "FOO " to " BAR"

       yeah sure environment variables can have spaces in them, that's not a mistake that is just going to cause problems

       @foone not sure if I should be proud for getting this one right immediately. I haven't done any batch file programming in 25 years, but it was one of the first languages I was exposed to, so some of the nonsense stuck. (Limited access to real language environments on un-networked home MS-DOS PCs meant that I had to turn to desperate measures to scratch the "I want to program stuff" itch. Super grateful that MS-DOS 6.0 actually had decent help files.)
