How to compile MicroCalc
------------------------

With TC.EXE:

  1. Run TC.EXE
  2. In the Project pulldown menu specify the project name "MCALC.PRJ"
  3. From the main menu select the Run option

With TCC.EXE:

  Compile from DOS with the following command line:
    TCC mcalc mcparser mcdisply mcinput mcommand mcutil mcmvsmem.obj

In both cases, compiling under a large data model (COMPACT, LARGE, or HUGE)
will give you much more memory for your spreadsheets.

The MicroCalc parser
--------------------

The state and goto information for the parser was created using the UNIX YACC
utility.  The input to YACC was as follows:

%token CONST CELL FUNC
%%
e : e '+' t
  | e '-' t
  | t
  ;
t : t '*' f
  | t '/' f
  | f
  ;
f : x '^' f
  | x
  ;
x : '-' u
  | u
  ;
u : CELL ':' CELL
  | o
  ;
o : CELL
  | '(' e ')'
  | CONST
  | FUNC '(' e ')'
  ;
%%

Additional MicroCalc information
--------------------------------

Formulas are entered as text.  MicroCalc will determine if what you entered
is a legal formula or text.

Cell names in formulas are typed in with the column followed by the row.

Examples:

A1+A2
B6^5

To sum a group of cells, put a colon between the first cell and the last
cell in the group.

Example:

A1:A10 sums all of the cells from A1 to A10 and puts the result in the
current cell.

The available MicroCalc functions are:

ABS - absolute value
ACOS - arc cosine
ASIN - arc sine
ATAN - arc tangent
COS - cosine
COSH - hyperbolic cosine
EXP - exponential function
LOG - logarithm
LOG10 - base 10 logarithm
POW10 - raise argument to the 10th power
ROUND - round to the nearest whole number
SIN - sine
SINH - hyperbolic sine
SQR - square
SQRT - square root
TAN - tangent
TANH - hyperbolic tangent
TRUNC - return the whole part of a number

Examples:

TRUNC(A1)
SQRT(SQR(34.5))
ABS(TRUNC(B16))
