Greetings -

		I am confused!  Let's start with the basics: PROGRESS(tm)
currently has two products that interface to 3gls (Host Languages).

The first product Host Language Call (HLC) is used if the user is logically
in the database/PROGRESS(tm) process and the developer choose to "CALL"
a 3gl routine.

The second product Host Language Interface (HLI) { AKA Embedded SQL } is 
used if the user is *NOT* logically in a PROGRESS(tm) process.  This allows
the developer to "SELECT" data from a PROGRESS(tm) Database.

In your situtation where you have a PROGRESS(tm) RDBMS Server running on the
Network Server and a User running on a Network Client, You should use HLI
to "REQUEST" the data from the Server.

		I hope this helps!
			Bye,

Not that I know about but THINC has a Email Group for PROGRESS(tm). It is a
mailing list for discussion of all relevant aspects of the PROGRESS(tm) RDBMS.
