Does anyone know how I can get the value of an environment variable
under windows NT using delphi 2.0. I'm interested in passing the value of
environment variable "QUERY_STRING", and its length, to my CGI program
written in Delphi 2.0 running against MS Internet Server.

See the on-line documentation for GetEnvironmentVariable

(I am working on a class that provides a single interface for
environment variables in Delphi 1.0 and Delphi 2.0. It's mostly
finished, and will appear on the Tempest Software website when it is
ready.)

GetEnv has been a function in Borland Pascal forever... for some reason they
left it out of Delphi 2.0.  But, make sure you use the Windows unit, and then
..

Function GetEnv( S : STRING ) : STRING;

Var
  Name   : Array[0..128] of CHAR;
  TheVal : Array[0..256] of CHAR;

BEGIN
  StrPCopy( Name, S );
  TheVal := '';
  GetEnvironmentVariable( Name, TheVal, 256 );
  Result := StrPas( TheVal );
END;

This is Delphi 2.0 and we have Big Stirngs that are pChar castable so
how about:
Function GetEnv( S : STRING ) : STRING;

BEGIN
  SetLength(Result, 500);
  SetLength(Result,
    GetEnvironmentVariable( pchar(S), pchar(Result), 500));
END;
