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. |
