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.
