Editor

In order to learn to use POP-11 using our ``teach'' files on the computer, you may need to learn to use the Poplog editor called VED or XVED. XVED is the more up-to-date version that allows many of the commands to be chosen by mouse clicks. In what follows, I'll refer to VED to mean either VED or XVED. Normally your main initial task would be to learn VED. You will find that VED provides an ``interface'' to most of your activities on the computer.

However as part of the Prolog course you learned the text/program editor Emacs. So you have four choices:

1. Stick with Emacs and you'll have less to learn, but you won't be able to make use of the special facilities provided by Ved's integral relationship to Poplog.
2. Learn VED. This is an extra load, but most of the written and online material largely assumes that you will have learnt it.
3. Make VED look a bit like Emacs. This makes some of key bindings in VED the same as those in Emacs. (See help emacs).
4. Use Emacs but customize it to partially integrate it with Poplog. (See help emacs).
