Suggestions for working on this site.
1) If the text is too big for the window, a scroll bar will automatically
appear. You can use it to view the remainder of the text. Occasionally, a
scroll bar will appear when all of the text has been displayed except for
a blank line.
2) If you must leave this site, select the "exit" item from the File menu.
If you plan to return later, you may want to use the Bookmark button to set a
bookmark to the page you are on. With the bookmark set, you may go directly
to the designated page when you restart.
3) You may use the "index" page to jump directly to the topic of interest.
This is helpful when you have already completed a sequence and you want to
proceed to another without visiting all of the intervening pages.
4) Occasionaly, going to a new page may "reset" the "back button."
If you want to go back to a pevious page when the "back button" is not
enabled, select the "close" item from the File menu. This will close
the page you are on and all subsequent pages and restore you to the
previous page sequence. Be carefull not to select the "exit" item unless
you want to stop completely and have set bookmarks if you plan to return.

All occurances of the labels and names must be identical. That is: 1. Case sensitivity, - John != john. 2. Delimeter sensitivity - multiword identifiers must always have the same number of blanks between the words. Big john != Big john.
Do not use commas in numbers. That is, type 100000.00 - NOT 100,000.00.
You must use possessives to combine row and column names. So in the table below, use "little john's age", not "little john age"
-------------------------- | | age |weight| -------------------------- |little john| 12 | 130 | -------------------------- |big john | 14 | 110 | --------------------------
Expressions must be "algebraic" not "English." That is:
age + weight - Yes add age to weight - No
