Do you mean client applications?  If so, you can write your own using
Sybase's DB-Library (a library of C routines that allow a C application
to converse with SQL Server).  There are also client applications
available like dBASE IV.  I don't have a list of them but there are more.

>If so, what networking is needed on the DOS end?

A DOS DB-Library client can, CURRENTLY, talk to:

	an OS/2 SQL Server over Lan Manager
	an AT&T Unix System V SQL Server over Starlan
	a Sun or Pyramid Unix SQL Server over TCP/IP
		Excelan or PC-NFS
	a VAX SQL Server over DECnet
		CommUnity-DOS or DECnet-DOS

>Will it work with FTP's TCP/IP for DOS?

	soon

>Will it work with NETBIOS?

	DB-Library does not specifically talk NETBIOS

>How much does it cost?

	call Sybase

>What Protocols/Networks does DB-Net Support?

	see above

>Is there a client or front-end available for VAX/VMS or Apollo?

	Sybase does have VAX and Apollo front-ends

>If I wanted to write a client or front-end for DOS, what would I
>need from Sybase? 

	PC DB-Library
	PC DB-Net of your choice (see above for list of currently avail)

>How does DB-Library interface to the Networking/Communications?

	DB-Library makes calls into DB-Net.  DB-Net makes calls into
	a network vendors library - some examples: Excelan's Socket
	Library, DECnet-DOS's C Task-To-Task Interface Library, etc.

>Is source code available for DB-Library or DB-Net available? How much?

	call Sybase

>How easy is it to port DB-Library or DB-Net to other environments?

	straightforward

>Where does Open Server fit in? 
>How does Open Server allow me to access a DB2 database?

	I'm the PC DB-Library/DB-Net person so I can't answer that, sorry.

>Thank-you.

	You're welcome.
