- March 1991
- ==========
-
- This revision now handles variable screen lengths. Thus, if you have an
- ANSI.SYS or equivalent which allows 43 or 60 lines, e2 can be set to
- use it. This is standard for OS/2; I don't know if someone has done
- it for Dos. In my version, all you can do is reduce the no. of lines.
-
- To use, either specify
- -lines=N
- on the command line, or set your TERM environment as follows:
- set TERM=ibmpc2.N
-
- On an OS/2 VIO window, N will go up to 102, but it's not very useful since
- you have to scroll the PM window to see all of the e2 window!
-
- Missing from the previous documents was a mention of the EFLAGS environment
- variable. Here are some useful bits:
-
- set EFLAGS=<string>
- where <string> is made up from any of:
- b turn off the *!%$"!!! bell
- i default to Insert mode
- l default to LF separators rather than CR-LF
- r default to Regular expression mode
- w default to auto-Wrap mode

- =============
-
-
- Here is the Rand editor for the PC. It is heavily based on the original
- Unix version, as are the documents, but the operation on OS/2 or Dos
- should be clear in most cases.
-
- Recently, I managed to get external program operation, including the fill
- and justify filters, to cough into life. The internal jiggery pokery
- to get this to go for both OS/2 and Dos is best glossed over :-) however,
- the user should be aware of restrictions:
-
- a) it's heavy on file descriptors (handles). External filters
- which open lots of files may fail.
-
- b) programs which interact with the keyboard can cause problems.
-
- The fill, justify and center filters should be OK. Things like grep, if
- you have it, are also quite useful - e.g.
-
- <Mark a block>
- <Esc> run grep -v zork
-
- will remove all lines in the block containing the string "zork".
-
- Generally, I recommend practice on unimportant data to gain confidence.
-
- The "call" command to execute external commands and return does not yet
- function correctly. Maybe one day ... Meanwhile, the sequence
- ^Z
- command
- e2
- achieves the same effect in not many more keystrokes.
-
- This version will not drive the serial port under Dos (ctty com1:), though
- I have a version that does. I may try to combine the functions in future.
-
- Owing to formatting limitations, some of the documents contain things like
-
- @east@ @west@
-
- and so forth. These, of course, represent the cursor arrows.
