Turbo Pascal 5.5 / Windows 95 LFN Question

Hi folks.  Does anyone know of a way to integrate long filename
support into older, character mode TP programs?  I've got some older
directory utilities I'd like to update, nothing fancy just directory
listing and file copying.  I'd like to find the information on the
net, as opposed to buying Microsoft's programmer's guide for Windows
95. Yuck!  Thanks,
