- INTRODUCTION
-
- MicroCalc is a tiny spread sheet program a la VisiCalc. It is
- provided with the TURBO-Pascal system as an example program.
-
- Since MicroCalc is only a demonstation program it has its limita-
- tions (which you may have fun eliminating):
-
- * You can not copy formulas from one cell to others.
- * You can not insert and delete lines or columns.
-
- In spite of its limitations MicroCalc does provide some interest-
- ing features among which are:
-
- * 11 digits floating point reals (Thanks to TURBO Pascal!)
- * Full set of mathematical functions (SIN,COS,LN,EXP etc.)
- * Built in line editor for text and formula editing.
- * Text can be entered across cells.
- * Once entered a formula is protected from accidental erasure.
- .PA
-
-
- In addition to this MicroCalc offers all the usual features of a
- spread sheet program:
-
-
- * Load a spread sheet from the disk.
- * Save a spread sheet on the disk.
- * Automatic recalculation after each entry. (May be disabled).
- * Print the spread sheet on the printer.
- * Clear the current spread sheet.
-
- The spread sheet is an electronic piece of paper on which you can
- enter text, numbers and formulas and have MicroCalc do calcula-
- tions automatically.
-
- The next page shows the electronic spread sheet.

- A 5 Formula:
- (A1+A2+A3+A4+A5)
- -----------------------------------------------------------------
-
- In the example the next last line shows that the active cell is
- cell A5 and that A5 contains a formula: (A1+A2+A3+A4) which
- means that the numbers in A1,A2,A3 and A4 should be added and
- placed in A5.
-
- The formula can be abbreviated to: (A1>A4) meaning: add all cells
- from A1 to A4.
- .PA
- You move the cursor around just like you do in the TURBO editor:
-
- (Up)
- Ctrl-E
- (Left) Ctrl-S Ctrl-G (Right)
- Ctrl-X
- (Down)
-
- ---> On the IBM-PC you may also use the arrows. <---
-
- A cell may contain a number, a formula or some text. The type of the cell
- and its coordinates are shown in the bottom left corner of the screen:
-
- A 5 Formula: (Means that the current cell is A5 and that it
- contains a formula)
-
- A 1 Text (Cell A1 contains text)
-
- A 2 Numeric (Cell A2 contains a number and no cell references)

- Summary of MicroCalc
- Cells are denoted A1 through G21 giving a total of 147 cells.
-
- Summary of standard functions and operators:
- ABS, SQRT, SQR, SIN, COS, ARCTAN, LN, LOG, EXP, FACT
- +,-,*,/, ^ to raise to any power e.g. 2^3 = 8
- Futhermore the operator '>' can be used to denote a range of cells to add.
-
- Entering data
- To enter data in any field move the cursor to the cell and enter the
- data. MicroCalc automatically determines if the field is numeric or a
- a text field.
-
- When moving between fields:
- ^S,^D,^E,^X move left right up and down.
-
- When editing a field
- ^S,^D moves left and right. ^A,^F moves to beginning/end of line.
- DEL,^G deletes left or right character.
- ^V (or Ins on the PC) changes between insert-/overwrite mode.
- ESC makes it possible to regret changes and to edit an existing cell.

- Summary of commands
-
-
- / will restore the screen
- Q will Quit MicroCalc
- L will Load a spread sheet from the disk.
- S will Save a spread sheet on the disk.
- R will Recalculate
- P will Print the spread sheet.
- F makes it possible to change the output format for numbers.
- A switches Autocalc ON and OFF
-
- Note: to use scientific notation use the the F command and enter minus one
- -1 for the number of decimals.

- EXAMPLES
-
- The following are examples of valid cell formulas:
-
- (A1+(B2-C7)) subtract cell C7 from B2 and add the result to cell A1
- (A1>A23) the sum of cells: A1,A2,A3..A23
- (A1>B5) the sum of cells: A1..A5 and B1..B5
-
- The formulas may be as complicated as you want:
-
- (SIN(A1)*COS(A2)/((1.2*A8)+LN(FACT(A8)+8.9E-3))+(C1>C5))
-
- To edit an existing formula or text simply move to the cell and
- press ESC, make your changes and press <RETURN>. If you make
- a mistake you may press ESC again, the old value of the cell will
- then be restored.
