ses-calculate-cell
ses-calculate-cell is a compiled Lisp function in `ses.el
'.
(ses-calculate-cell ROW COL FORCE)
Calculate and print the value for cell (ROW,COL) using the cell's formula
function and print functions, if any. Result is nil for normal operation, or
the error signal if the formula or print function failed. The old value is
left unchanged if it was *skip* and the new value is nil.
Any cells that depend on this cell are queued for update after the end of
processing for the current keystroke, unless the new value is the same as
the old and FORCE is nil.
