Returns the String associated with an operating system environment variable. Not available on the Macintosh
Syntax
Environ({envstring | number})
The Environ function syntax has these named arguments:
| Part | Description |
|---|---|
| envstring | Optional. String expression containing the name of an environment variable. |
| number | Optional. Numeric expression corresponding to the numeric order of the environment string in the environment-string table. The number argument can be any numeric expression, but is rounded to a whole number before it is evaluated. |
Remarks
If envstring can't be found in the environment-string table, a zero-length string ("") is returned. Otherwise, Environ returns the text assigned to the specified envstring; that is, the text following the equal sign (=) in the environment-string table for that environment variable.
If you specify number, the string occupying that numeric position in the environment-string table is returned. In this case, Environ returns all of the text, including envstring. If there is no environment string in the specified position, Environ returns a zero-length string.
