In esProc, if a cell has a value, then its name can be used to reference the cell value in a computational cell or an executable cell. A cell possessing a value can be a constant cell, a computational cell or other types of cells got assigned by the executable cell. The name of a cell includes the letter representing the column in which the cell is located and the integer – the serial number of the row it resides. In the above cellset, the expression in cell A2 calls the value of cell A1. The following is another example:

esProc_start_install_3

But different to Excel, in esProc, the letter in the cell name must be capital.

esProc provides lots of functions to handle various kinds of data computing. For example:
