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))
