The function SysSearchPath()

If a filename is passed to the function <SysSearchPath without an 
extension, but WITH a trailing dot, the function will return the filename 
WITHOUT the trailing dot (provided, of course, that the file exists); 
e.g.: 

 
   newName = SysSearchpath( 'PATH', 'test.' )

returns C:\test if that file exists (and C:\ is in the PATH variable).
