EnvStr function

Targets: MS-DOS, OS/2, Win32


Dos Unit

Returns a specified environment string.

Declaration:
function EnvStr(Index: Integer): string;
Remarks:
Index is the number of the environment variable, for instance, the first variable is one, second is two, and so on. An invalid index returns an empty string.

EnvStr returns a string in the form of (VarName=String). If the order of system environment variables is unknown then use GetEnv to retrieve a variable by name.

Example: uses Dos; var i : Integer; begin for i := 1 to EnvCount do WriteLn(EnvStr(i)); end. See also:
