Return an environment variable by index.

function GetEnvironmentString( |
Index: Integer |
):String; |
GetEnvironmentString returns the Index-th environment variable. The index is 1 based, and is bounded from above by the result of GetEnvironmentVariableCount.
For an example, GetEnvironmentVariableCount.
| Remark: | Note that on Windows, environment strings can start with an equal sign (=). This is a trick used to pass the current working directory to a newly created proces. In this case, extracting the variable name as the characters before the first equal sign will result in an empty name. |
If there is no environment, an empty string is returned.
