Update information for Dr. Shaw's DOS Shell
1/23/86
Be sure and read the information on Menu Limitations in the
Manual. Menus do not run on DOS versions below 3.xx.
Ctrl-T now deletes the command or phrase to the right, not
the entire line to the right.
Home will move to the beginning of the command - line.
End will move to the last character on the command - line.
! will display a history of the other 19 commands in the
buffers.
!# (where # is a number from 1 - 19) displays the given
command line buffer.
Backspace and ^H now perform backspace-delete.
Del now deletes the character under the cursor (like ^G).
A bug concerning the Date and Time commands has been fixed.
2/25/86
The Shell still uses about 44-48k of memory. To verify
this, run the MEM command and note the available memory. Then
run another image of the Shell while the current Shell is already
running. Run the MEM command again and subtract the difference
in available memory. Type EXIT to return to the first Shell.
The current version is only about 24K on disk (it was 32K)
before. I hope to get memory usage down to 32K eventually,
assuming I can squeeze some new features in at the same time.
I have a number of features I will probably add. I like to
take the time to consider whether something is really worthwhile
before adding it, so do NOT consider this a promise that these
will be added, or soon. However, these may include:
* Improved alias capabilities.
* A sophisticated shell file interpreter.
* Use of the DOS environment strings and prompt.
* Argument expansion specification in CONFIG.SH.
* Shell configuration modify and show commands.
* Command Line Macros.
* Specification of the History length in CONFIG.SH.
* All sorts of other goodies! If you have an idea,
share it with me!
