2. Basic Use of esProc
Run esProc main program to open esProc and click new button to create the cellset file.
On the left is the cellset section, the active cellset files you are operating are shown here; on the right, the upper area is the valueview section and the lower area is the variable section. Value view section and variable section can be retracted and expanded easily.
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:
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:
And auxiliary function for editing functions can make code-writing in cells more easily. During editing expressions in cells, press Alt+↓to open/close the auxiliary function for editing functions. On the auxiliary interface for editing functions, you can see function syntax, function reference and other information:
