The larger the organization, the finer the line between a "feature" and a
"design error".  For this, send Bill Gates a thank you note.

From the Compaq MS-DOS/Version 3 Reference Guide: "If the preceding program
returns an exit code that is equal to or greater than the specified NUMBER,
the condition is true.  If you use the NOT parameter, the preceding error code
must be less than NUMBER".  So "errorlevel 0" is always true, and  "not
errorlevel 0" is always false.  Enjoy.
