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.
|
|||
|
|
|
|||
|
|
