Return the number of environment variables.
If Count() returns N, then you can call Get(x) with 0 <= x < N.
Puts in s
the n
th environment variable as a string containing a key, equal sign and possibly a value (i.e. 'PATH=/usr/bin').
n
must be in range 0 <= x < N, where N is the result of Count().
Returns a full path to the application directory. That is the directory where the executable file of the currently running program resides.
It might not be logically possible to determine application directory in some cases on Linux/Unix systems.
Puts in val
the value of the environment variable with the given name
.
If there is no such variable, puts an empty string in val.
Puts in s
the language of the user interface (the OS) as a lower case 2-character string.
Examples: 'en', 'ru'.
