JACAL HELP
You are typing at Jacal's top level. Typing "qed;" will exit Jacal.
If you are running Jacal under Scheme, you can always reenter your
session by typing "(math)".
When you see the line "--more--" printed by Jacal, type <space>
followed by <return> (or <enter>) to see more of what is being
printed. Type "q" or "Q" to stop the printing of the expression or
file.
There is a limited online help system. Type "commands();" to see all
available commands. Typing "describe(describe);" will give a short
explanation of describe. Typing "example(describe);" will give an
example of the use of describe. Not all commands have examples.
Jacal also has flags that can be set to control features of operation.
Typing "show all;" will list them.
A manual in TeX format is included in the distribution. A printed
copy of the manual is supplied with Jacal floppy disk. To receive the
IBM PC floppy disk with the documentation, source, and executable
files, send $99.00 to: Aubrey Jaffer, 84 Pleasant St., Wakefield MA
01880 USA.
When Jacal thinks that a sub-expression is missing from an input
expression, it will put a "?" in the place it expected the
sub-expression. This "?" can be treated as a regular variable. You
can use this to modify the expression (using Eliminate) so that you
don't have to retype the entire expression.
