Block Space Requirements (Block	Cluster Size = 1):
	
Disk space required for installation:  9,000 blocks(4,608K bytes)
						       

Disk space required for use (permanent): 9,000 blocks (4,608K bytes)
						       

These counts refer to the disk space required on the system disk.  The sizes
are approximate; the actual sizes may vary depending on the user's system 
environment, configuration, and software options.

The minimum supported memory for this application running in a standalone
DECwindows environment with both the client and server executing on that
same is 6 mg.

The performance and memory usage of DECwindows applications are particularly
sensitive to system configuration.  Less memory may be required on the client 
system (the system where the software is installed and executed) if the server
(the component that displays the application) resides on another system.  More
memory may be required on a system with several applications running or may
be desirable to improve the performance of an application.

The minimum supported memory is the minimum that will allow the product to 
run adequately.  For optimal performance of the product, the recommended 
memory is 16 mg.

OPTIONAL HARDWARE

None

CLUSTER ENVIRONMENT

This layered product is fully supported when installed on any valid and 
licensed VAXcluster or Local Area VAXcluster configuration including 
VAXcluster configurations accessing a common system, without restrictions.


SOFTWARE REQUIREMENTS

VMS Operating System V5.1

This product may run in either of the following ways:

^ Stand-alone execution - Running the X11 display server and the client
  application on the same machine.

For stand-alone execution, the following DECwindows components must be 
installed on the machine:

^ VMS DECwindows Compute Server
^ VMS DECwindows Device Support

For remote execution, the following DECwindows components must be installed
on the machines:

Server Machine					Client Machine

VMS DECwindows Device Support			VMS DECwindows Compute Server
						(runtime support)
