# getenv

Definition: | object x = getenv(string s)
Description: | Return the value of a DOS environment variable. If the variable is undefined return -1.
pwa/p2js: | Not supported.
Comments: | Because either a string or an atom (-1) might be returned, you should probably assign the result to a variable declared as object. There is also a setenv() routine, as yet undocumented [DEV].
Example: |
    ?getenv("ALLUSERSPROFILE")  -- "C:\ProgramData"
Implementation: | See builtins\penv.e (an autoinclude) for details of the actual implementation.
