Summary: 


Being a new reader of this news group I may be asking for help with something
that has already been discussed on the net.  

What I need is a program which maps drive names (existing or virtual) to
particular directories on a disk (especially a hard disk).  The program would 
be such that it would stay resident once loaded, and hopefully allow the
user to specify what directory to map a drive letter to through the use 
of interactive commands.

I guess this could be considered sort of like an extended DOS assign command.

The purpose of this is to aid in the installation of programs on a hard disk.
A lot of old programs don't support directories (quite a few new ones too!),
and I would find it much more convienient when transferring a program to the 
hard disk to keep the program and associated files (overlays etc.) in one 
directory.  The data created would be stored in another directory.  Since 
a lot of programs allow specification of where a file is created/loaded 
from by disk letter identifier I felt a program such as described would be most
useful.

Has any one heard of anything like this?  

If not I may write one myself.  I was thinking of doing this by intercepting
the INT 21 dos function call.  Any hints or suggestions on this would be most
helpful.

Thanks in Advance
