- INTRODUCTION
-
- MicroCalc is a tiny spreadsheet program "a la MultiPlan". It is provided
- with the Turbo Basic system as an example program.
-
- Since MicroCalc is only a demonstration program, it has its limitations
- (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 interesting
- features among which are:
-
- * 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.
- * DOS acces
- * Color cells
- .PA
-
- In addition to this, MicroCalc offers all the usual features of a
- spreadsheet program:
-
- * Load a spreadsheet from the disk.
- * Save a spreadsheet on the disk.
- * Print the spreadsheet on the printer (or to a file)
- * Automatic recalculation after each entry (May be disabled).
- * Init (Clears) the current spreadsheet.
-
- Note :
-
- The spreadsheet is like an electronic piece of paper on which you can
- enter text, numbers and formulas and have MicroCalc to do calculations
- automatically. The cells are the intersections between lines and columns.
-
- ( The next page shows the Spread Sheet ... )
- .PA
- This is the electronic spreadsheet :
-
- A B C D E F G
- 1 22.45
- 2 1.00
- 3 2.00
- 4 3.00
- 5 28.45
- .
- .
- 21
- [A5,Formula] type / for Commands, F2 For Edit AutoCalc is ON
- (A1+A2+A3+A4)
-
-
- Cells are denoted A1 through G21 giving a total of 147 cells.
-
- 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) (add all cells from A1 to A4).
- .PA
- You move the cursor around just like you do with the Turbo Basic editor :
-
- (Up)
- Ctrl-E
- (Left) Ctrl-S Ctrl-G (Right)
- Ctrl-X
- (Down)
-
- ( On the IBM-PC you may also use the arrow keys. )
-
- 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:
-
- [A5,Formula] Means that the current cell is A5 and that it
- contains a formula.
-
- [A1,Text] Cell A1 contains text.
-
- [A2,Numeric] Cell A2 contains a number.

- Summary of MicroCalc functions
-
-
- Summary of standard functions and operators:
- ABS, SQRT, SQR, SIN, COS, ARCTAN, LN, LOG, EXP, INT, SGN, FACT (factorial)
- +,-,*,/ and ^ to raise to any power : e.g. 2^3 = 8
- Furthermore 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 cell is numeric or a
- a text cell. Cell beginning with + - ( . 0 1 2 3 4 5 6 7 8 9 is numeric.
-
- When moving between cells:
- ^S,^D,^E,^X move left, right, up, and down.
-
- When editing a cell
- Tab Left,Tab Right moves left and right. ^A,^F moves to begin/end of line
- ^G or DEL deletes left or right character.
- ^V or Ins changes between insert/overwrite mode.
- F2 to edit an existing cell. ESC makes it possible to regret changes
- .PA
- COMMANDS OF MicroCalc
- The commands are available when you strike the / character :
-
- A switches Autocalc ON and OFF
- B switches Border ON and OFF
- C to change cell Color
- D acces to Dos (or execute a DOS commands)
- F to change the output Format for numbers
- Note: to use scientific notation enter -1 for the number of decimals
- G to Goto a specified cell
- H the Help screens
- I to Init (clear) the SpreadSheet
- L to Load a spreadsheet from the disk
- P to Print the spreadsheet to the printer (or a file)
- Q to Quit MicroCalc
- R to Recalculate the Spread Sheet
- S to Save a Spread Sheet on the disk.
- U to Update (to restore) the screen
-
- To edit a cell content : Simply move to the cell and press F2 key,
- make your changes and press RETURN key (or press ESC to cancel).
- .PA
-
- 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>A21) the sum of cells A1,A2,A3..A21
- (A1>B2) the sum of cells A1,A2, B1,B2
-
- 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 try MicroCalc, now use the L command to Load the file MCDEMO
-
-
- Note : If you run MicroCalc with a FileName parameter, this File will be
- loaded automatically : (e.g. MC mcdemo).
