- Greetings!
-
- E is a little programming editor I wrote and am releasing into the public
- domain. It keeps the file being edited in RAM and makes use of all available
- standard memory, allowing editing of large files. It provides a full set of
- cursor movement commands, block and line move and delete functions, and find
- and replace operations. Block operations may be directed to use an internal
- buffer or another file. It's written in TASM for speed and compactness (I've
- included the source so you can make your own modifications if you want).
-
- E is simple enough that it doesn't need much extra documentation. Just fire
- it up and press F1 for help. Here's an expanded version of the help screen
- with some additional comments.
-
- left left arrow, ^s The Ctrl-letter forms of the
- right right arrow, ^d cursor commands may be harder to
- word left ^left arrow, ^a remember, but don't require that
- word right ^right arrow, ^f you lift your hands from the home
- start of line Home keyboard position.
- end of line End
- up up arrow, ^e 'Delete to end of line' and
- down down arrow, ^x 'delete line' put the clipped lines
- page up PgUp, ^r or portions into a delete buffer
- page down PgDn, ^c from whence they may be undeleted
- start of file ^PgUp using Ctrl ^. This is the easiest
- end of file ^PgDn way to move a few lines: delete
- backspace backspace the lines, move the cursor to
- delete Del the new location, then undelete.
- delete word left ^[
- delete word right ^] The block commands marked with
- delete to end of line ^\ a * will use a file (you'll be
- delete line ^- prompted for the name) if the shift
- undelete line ^^ key is pressed along with the Alt-
- toggle insert mode Ins letter combination. Otherwise an
- help F1 internal buffer will be used. These
- mark start of block @m commands only work on whole lines.
- copy block @c * Copy will put a copy of all marked
- delete block @d * lines (between the line where you
- insert block @i * pushed Alt M and the present cursor
- empty block buffer @e * location) in the buffer or a file.
- unmark @u Delete does a Copy and removes the
- find @f + original lines. Insert inserts the
- replace @r + contents of the file or buffer above
- find/replace all @= + the present line. To move text, use
- save and continue @s Delete then Insert. To move text
- save and exit @x between two files, Delete or Copy to
- kill save on exit @k a scratch file, then Alt O to change
- label (0-9) @l files, then Insert the scratch file.
- go to label (0-9) @g
- jump to line # @j Find and Replace will use the
- set tab width @t strings last entered if the shift
- toggle autoindent @a key is down. Replace must always
- be used immediately after Find. Use
- @ = Alt, ^ = Ctrl. Find/Replace All if you're sure you
- * = to/from file if shifted want to change all occurrances of a
- + = use previous string(s) if shifted string. Otherwise use shifted Find
- and Replace selectively.
-
- Alt O will save the current file and prompt for the name of a new file to
- be loaded. Use Alt S to save and continue, Alt X to save and exit, and Alt K
- followed by Alt X to discard any changes made and exit.
-
- Autoinsert mode lines up the start of each new line (after Enter) with that
- of the line above it. Use Alt A to toggle this on or off. When off, each
- new line will start at the left-hand margin.
-
- You can mark your place in the program with Alt L, which prompts you for a
- label from 0 to 9. Pressing Alt G, then the label number will return you to
- this spot. Alt J will prompt you for a line number to jump to.
-
- Whenever you are entering something in response to a prompt such as a find
- string or file name, entering a null string (just Enter) will cancel the
- command.
-
- I'd appreciate hearing about any bugs, and welcome any other comments. I
- may release an upgrade one of these days. To contact me, leave a message on
- the EXEC PC BBS (1-414-964-5160) or write me at the address below. Please
- enclose a stamped, self-addressed envelope if you need a reply. Sorry, I can't
- promise any support. Thanks for trying E!
