- 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.
