Enhancing the HP e3000 User Interface

Robelle Qedit™ for Windows™—Windows-enabling the HP e3000
Qedit for Windows client/server software provides a modern Windows interface to HP e3000
source code development and text file editing. Consisting of a Windows editing client and an
MPE/iX editing server which are connected seamlessly through the TCP/IP protocol, Qedit for
Windows can edit any type of file available on the HP e3000. To accommodate today’s multi-
platform environment, the Qedit server is also available on HP-UX—extending multiple file
capability to MPE, HP-UX, and Windows.
Client/Server Architecture
Qedit’s client/server architecture utilizes a seamless TCP/IP connection, which translates into
instant access to host HP e3000 files. The host files are not transferred to the PC; instead they
remain resident on the host HP e3000 or HP-UX system. Qedit for Windows uses Robelle’s
“smart caching” technology to send just the desired portion of the file to the client, filling up the
user’s screen around those lines. When changes are made, the client sends the minimum amount
of information back across the connection where the Qedit server applies the changes directly
to the file on the host HP system. Simply put, the Qedit client handles the user interface while
the Qedit server performs the editing operations—and all the mechanics are invisible to the
user.
Ease of Use
Qedit’s graphical user interface shortens the journey to productivity in HP e3000 usage and
development, especially for newcomers to the platform. All the standard “Windows-y” editing
functions such as cut/copy/paste are available. These functions work on all types of files
supported by Qedit for Windows—local and network PC files, HP e3000 and HP-UX files. Other
productivity-enhancing features include split screen, rectangular selection for column editing,
multiple files, easy file selection, powerful search and replace, auto-indent, etc.
Performance
Because Qedit’s unique client/server design transfers only the required parts of the file and not
the whole file, access is virtually instant with minimal demands on the network. There is no
need to wait for long downloads and uploads when opening and saving host files.
Scalability
Qedit for Windows offers high scalability in two areas: file size and network connection. Qedit
for Windows can handle huge files such as spoolfiles, datacomm traces, data files, and
COPYLIBS. Current capabilities are files up to 99,999,999 lines long and 8,172 characters wide.
Additionally, Qedit offers high-speed performance scalable from fast local networks to slower
remote connections. Designed to serve a distributed computing environment, Qedit allows users
at remote sites to access their host files over a modem via TCP/IP or via an Internet connection.
