This document contains information about running Parts on a 
Macintosh II.

The Macintosh implementation of Parts has all the functionality of the 
IBM PC implementation, as well as some specific features not found on 
the IBM PC.  Some features are invoked differently due to the nature of 
the Macintosh.

Application Memory Size
Parts is set up to run in a 1024K region. If Parts seems to be 
misbehaving you might try increasing the suggested size. You change the 
memory size allotted to Parts by single-clicking on the application 
PARTS, then typing an Apple + I to get the Information Box on the 
screen. The suggested size appears in a box in the lower right.


Window Sizing and Placement
You may move the window at any time. You may change the screen size 
whenever you see the grow box at the lower right. You may also click on 
the Zoom box. If you hold down the Option key when clicking on the Zoom 
box, the window will shrink down to nothing;  the next click on the Zoom 
box will restore it.

Color Monitors
You may change the trace and window colors by selecting Color Monitor 
under the Color Menu. You enable and disable a trace color by clicking 
on the name; a bullet signifies a selected trace color. Each click on 
the Window Color button cycles through the 8 basic Macintosh colors. Hit 
the return key or click on the DONE button when you are satisfied with 
your selection.

Parts saves the window information (size, placement, and color 
infomation) in a file named PartsPreference in the root folder of your 
hard disk when it exits, and reads it back when you start up.



Selecting operations with the mouse
Whenever a menu is presented at the bottom of the screen, you may 
either:
¥	type a return, which selects the default command.  The default 
command is in reverse video, and may be changed by using the left or 
right arrows on the keyboard;
¥	type the first letter of the command, or if it is preceeded by a 
number, that number;
¥	move the mouse over the operation and click on the mouse.

Reading and Writing Log Files.
A Log file is opened when you select 'Write to Log File' under the File 
Menu.  It will contain a history of what you type on the keyboard from 
that point on, until you either exit the application or select 'Close 
Log File'.  You may select 'Read From Log File' to replay what you have 
done. The log files are text files;  as such, you may use EDIT or 
another word processor them to change values.
You may insert lines which read:
	Pause
or,	Pause N
to have Parts pause (N seconds for the Pause N form) or until you hit a 
return (for the Pause form).

You may select About Parts under the Apple Menu to get the version 
number and your ID number.



Copying a Screen Image to ClipBoard
When a graph is on the screen, you may select Copy under the Edit Menu 
to copy it to the clipboard in PICT format.  You may then paste it into 
the ScrapBook, or into applications such as MacPaint.  If you hold down 
the option key when copying, the menus at the bottom will be copied; 
otherwise only the graph will be copied.  If the size of the Clipboard 
file would exceed 32K bytes, nothing will be copied to it and a bell 
will sound.

Copying a Screen Image to MacPaint¨ format file
When a graph is on the screen, you may select 'Write Image to MacPaint 
File' under the File Menu to save it as a MacPaint file.  You may save 
an image which is more complicated than by copying to the clipboard as 
outlined above.  A MacPaint image is always 576 pixels wide by 720 
pixels long, so your image will be padded with white space or clipped to 
fit.
