Editing a File
You are be prompted to enter the name of the file to edit. If you wish to start
with a new (empty) file, enter nothing for the file name (press
f1
to clear the
entry line if necessary); when you have finished typing in the fileÕs contents,
you get to name it on exiting from the editor. If you arenÕt sure of the name
of the file to be edited, you can use the wild card character *. For example, if
you enter
/user/*
you will be shown a list of all the files in the /user directory, as well as any
subdirectories, and you can pick a file, or navigate backwards or forwards
through the directory tree.
Running a File
LPL program files can be run from the LPL Copyright screen by pressing R.
The prompt for the file name is similar to that of the Editor, described above,
so use of a wildcard will allow file selection from a menu of matches.
The Shell Program
Pressing S launches the file “/Sys/Lib/StdShell Ó. When run, this program will ap-
pear as in Figure 5-16.
The rules are pretty simple: your one line entry must be a valid LPL function
definition, followed by
enter
. Entering a blank line will bring back the previ-
ous entry so you can edit it and try again. Pressing escape quits the program.
A Calculator
You can use StdShell as a calculator, by typing in the expression to be eval-
uated, then pressing enter. Use postfix notation, or else begin with a $. For
example
+ DelLn
¨
ClrEnd
¨
DelChar
¨
CapLock
¨
AnyChar
ok:
Figure 5-16. The program StdShell prompts for LPL commands or state-
ments, and executes them.
