SUMMARY
=======

When setting environment variables, the following commands produce different
environment variables:

  SET FIRST=one
  SET FIRST =two

MORE INFORMATION
================

The command SET now displays the following (along with all the other environment
variables):

  FIRST=one
  FIRST =two

Trailing spaces are not removed from the environment variable that is being set.
The variables are fully functional and may be addressed in batch files by using
the same syntax when referring to the variable. For example, the following line

  echo %FIRST %

will print the word "two" on the screen.

Additional query words: 6.22 3.00 3.10 3.20 3.30 3.30A 4.00 5.00 6.00
