<p>A computer program product for operating a spreadsheet application program in conjunction with a framework of a library of functions. In operation the spreadsheet operates in a first process in memory and a function from the library operates in a second process in memory, the second process being independent of the first process. The or each user defined function is adapted to be called from a cell in the spreadsheet application, the function being evaluated or executed in the second process to return a value which is shown in the cell. If the returned value cannot be shown in the cell an identifier is shown in the cell with the value being returned with a symbolic code. The unique identifier may be passed to another defined function outside the first process.</p> |
