2.1. What's on the Screen

When you launch SynCalc, you will notice an array of buttons.
what you think they should do. The others are explained below:

Most of them do exactly

At the top of the form you'll notice a large blank space. This is the expression field. It can
hold 400 characters, and if the expression gets too long for the field, a scroll bar will appear.

Some of the buttons may not appear exactly as they do above. SynCalc will check your
PalmOS device's system preferences for your preferred number format and use localized decimal
and thousands place separators. In all non-USA setups, the parameter separator character is ';' as
opposed to ','.

2.2. Basic Use and Menu Commands

Using SynCalc is extremely simple and intuitive. Enter the expression you would like to
evaluate by pressing buttons or writing in the graffiti area. Pressing the equal key or entering a
return stroke in graffiti will evaluate the expression. If this isn't you're first experience with a
calculator, then this step should feel quite familiar. The order of precedence for SynCalc
operations is listed in Appendix A.

The hard scroll buttons have a special purpose in SynCalc. On the main screen, these
buttons cycle through past calculations. The Scroll Up button goes back one expression (less
recent), and the Scroll Down button goes forward one expression (more recent). On all other
screens, the scroll buttons are used to scroll.

On-line help is available throughout the calculator. Tap the "i" button in the top-right
corner of forms to view the help. The "i" button in the "About SynCalc" dialog contains a brief
on-line manual for SynCalc.

SynCalc has three menus, Calc, Edit, and Options. In describing the use of menu
commands, please note that Menu Choice "Calc->View Console" means the "View Console"
choice under the "Calc" menu.

2.2.1.The Calc Menu

From this screen, you can view, edit, and clear these memory locations. This form has its own
menu which allows you to clear memory locations and use Edit commands.
* "Calc->View Calculation Log" will bring up SynCalc's printer tape of past calculations.
From this view you can copy text from the log or clear the log via the form's own menu choices.
* "Calc->View Console" will bring up SynCalc's text console. This menu item has the
same effect as tapping the small note icon to the left of the answer area. From this view you can
copy text from the console or clear the console via the form's own menu choices.
* "Calc->Edit Shortcuts" will allow you to add, delete, and modify SynCalc's shortcuts.
This menu choice has the same effect as choosing "Edit Shortcuts..." from the shortcut button
popup on the main screen.

which allows you to view information about all installed plugins and plugin functions.

There are several neat features that make using SynCalc very easy. Tapping on the answer
field will place "Ans" in the expression. When the expression evaluates, "Ans" is substituted with
the result of the last expression. You can also use the answer from the previous expression by
dragging the answer to the expression field or any text storage button (this will be explained further
in section 2.5). Another way to work with the answer is to enter an operator while the expression
