- This is the functions table. The program is now in the Lotus EDIT
- mode, edit or add a function and than press the ENTER key or just
- press the ENTER key for no changes. By typing the keyword FN followed
- by a file name (like FNC:\LOTUS\????.WK1) the user can define a
- spreadsheet which will be retrieved each time he uses the <c>alculate
- option. The spreadsheet C:\LOTUS\????.WK1 will be retrieved and
- will replace the current program. This way the user can use this
- program as a file manager for all his scientific and engineering
- spreadsheets.
-
-
- IMPORTANT
-
-
- All LOTUS rules apply here, the function should be written as a LABEL
- (with a prefix like "'") followed by "+" or "-" or the "@" character.
- The program stores the functions on a separate file FORMULAS.WK1 as
- LABELS. When the user chooses the <c>alculate option the program
- deletes the prefix and the label becomes a formula.
-
- The user can insert 240 character long functions from the keyboard.
-
- Now the description screen appears:

- The program has two modes:
-
- 1. One line description: type the description and press ENTER or just
- press ENTER for no changes and you are back in the edit menu.
- 2. Full document description: type FN and the file name you want to
- assign to the description file (EXAMPLE: FNC:\LOTUS\????.WK1) and
- press the ENTER key. This example means that the file is ????.WK1
- located at drive C: in the LOTUS subdirectory (the .WK1 extension.
- can be omitted). The program will switch to EDIT mode where the
- user can type the description document. Use the arrow keys to move
- through the lines. Don't press the ENTER key unless you are
- finished typing. The ENTER key exits the EDIT mode. The program
- can view only up to 76 character long lines, therefore start a new
- line after typing 76 characters.
-
-
- Note:
-
- If a description file is already exists and you press the ENTER key
- only, the program retrieves the description file.
-
-
- **** WARNING ****
-
- Because the program is now in the EDIT mode the Lotus keys are
- operative, however the user is strongly advised to use ONLY the UP,
- PGUP, DOWN and PGDN cursor keys keys to scroll through the lines, the
- program doesn't allow scrolling to the sides by hiding all the columns
- except the current column. Trying to unhide the columns MAY destroy
- the program code. For example: if by mistake you have pressed the "/"
- key press ESC to get back to the READY mode and then press F2 to enter
- the EDIT mode or just continue to type, or press ENTER to exit the
- description mode.
-
- Type FN???? (the file name is ????) and press ENTER, the next
- menu appears:
-
- Down Up Next Previous Edit Save
-
- Using the first 4 menu items the user can scroll through the
- description.
-
- Press <E> to enter the EDIT mode, when you are finished editing or
- typing the description file press ENTER to return to the previous
- menu.
-
- Press <S> to save the description file, the next prompt appears:
-
- File name (press ENTER for no changes) -
-
- Type the file name or press ENTER for no changes (????).
-
- As we mentioned earlier if a description file is already exists and
- and you press the ENTER key only the program retrieves the file.

-
- Press <n> to get the next prompt:
-
- Input the number of data points (10 minimum) - 30
-
- Type the number of data points to create the normal distribution
- graph and press ENTER. First the graph appears and then pressing
- ESC or ENTER brings the next screen:

- The column FA contain the original list of numbers. The column FB
- contains the 30 data points between the minimum value in FA and the
- maximum value in FA. The column FC contains the propability function
- values multiplied by the number of sample points in the original
- list in the column FA.
