N_GETENV( [ <cEnvar> ] )


Parameters

<cEnvar>
Name of an environment variable (upppercase).


Returns

N_GETENV() with no parameters returns the entire environment buffer as 
a string. Environment strings are separated by the null character 
CHR(0).

N_GETENV(<cEnvar>) returns the value of the environment variable, 
similarly to the Clipper function GETENV().


Example

// Get the current path, modify it...
save_path = N_GETENV('PATH')
N_MODENV('PATH', save_path + ';F:APPL\USER\DATA')
.
.
.
// ...then restore it.
N_MODENV('PATH', save_path)
