Comments

Environ$
returns a
String
, whereas
Environ
returns a
String
variant.
If variable$ is specified, then this function looks for that variable$ in the environment. If the variable$ name cannot be found, then a zero-length string is returned.
If VariableNumber is specified, then this function looks for the Nth variable within the environment (the first variable being number 1). If there is no such environment variable, then a zero-length string is returned. Otherwise, the entire entry from the environment is returned in the following format:
variable = value

Dim a$(1)
a$(1) = Environ("SITE_Root")
MsgBox "My CIMPLICITY project directory is: " & a$(1)
End Sub
