gettting BDE alias path

Is there a function call to get the directory path of a BDE alias? In other
words, I KNOW what the alias of the table to be used is, but I need to get
the directory path. I want to get this info. without starting a session or
opening a table.

If you could give me a reference, I would appreciate it.

I'm not sure why you say "without starting a session". A default session is
automatically started at runtime if your app uses any database controls -
that is, if any of your forms uses DB.pas. The initialization of DB.pas does
this...
Sessions := TSessionList.Create;
Session := TSession.Create(nil);
Session.SessionName := 'Default';

So the simplest way to convert an alias to a path is...

uses DB;

function AliasLocation(const Alias: string): string;
var
AliasParams: TStringList;
begin
AliasParams := TStringList.Create;
try
Session.GetAliasParams(Alias, AliasParams);
Result := AliasParams.Values['Path'];
finally
AliasParams.Free;
end;
end;
