Thank You for your response Wily.
I'm using FreePascal - latest. (Not using lazarus for this project)
I'm developing for both windows and linux primarily.
The function "GetEnvironmentVariable('namehere')" I was not aware of. I will
see if that works in FreePascal. Kylix I've heard of but I don't think I'm
using that.
To my knowledge the other functions I mentioned "call the Os for you" also,
they just cap the string length. I'm happy there might be a nice alternative
you mentioned. Thank you - and I'll look into this!

Jason,
I'm not exactly clear on a few things, including which "getenv," (just
referring to Linux here, right?) which Delphi (?) you're using, etc., but
couldn't you use Delphi's and Kylix's built-in GetEnvironmentVariable(Name :
string) : string function? which calls the appropriate OS code
automatically for you? (Nicely implemented in D7's SysUtils... which I'm
looking at now. )
Or barring that, one can always use the Windows API functions
GetEnvironmentStrings, GetEnvironmentVariable ...
Seems quite easy to use the built-ins. Here's the D7 version:
{$IFDEF MSWINDOWS}
function GetEnvironmentVariable(const Name: string): string;
const
BufSize = 1024;
var
Len: Integer;
Buffer: array[0..BufSize - 1] of Char;
begin
Result := '';
Len := GetEnvironmentVariable(PChar(Name), @Buffer, BufSize);
if Len < BufSize then
SetString(Result, PChar(@Buffer), Len)
else
begin
SetLength(Result, Len - 1);
GetEnvironmentVariable(PChar(Name), PChar(Result), Len);
end;
end;
{$ENDIF}
{$IFDEF LINUX}
function GetEnvironmentVariable(const Name: string): string;
begin
Result := getenv(PChar(Name));
end;
{$ENDIF}
