FPE: Deleted Screenshot and cleaned up yj - checked functions; user-defined user-defined functions Basic IDE; applying IDE; Basic IDE User-Defined Functions You can apply user-defined functions in $[officename] Calc in the following ways: You can program functions as add-ins. This method requires an advanced knowledge of programming. You can define your own functions using the Basic-IDE. This method only requires a basic knowledge of programming. Defining A Function Using %PRODUCTNAME Basic Choose Tools - Macros - Macro. Click the Edit button. You will now see the Basic IDE. Enter the function code. In this example, we define a VOL(a; b; c) function that calculates the volume of a rectangular solid with side lengths a, b and c: Function VOL(a, b, c)
VOL = a*b*c
End Function Close the Basic-IDE window. Your function is automatically saved in the default module and is now available. If you apply the function in a Calc document that is to be used on another computer, you can copy the function to the Calc document as described in the next section. Copying a Function To a Document In stage 2 of "Defining a user-defined function in Basic-IDE", in the Macro dialog you clicked on Edit . As the default, in the Macro from field the soffice - Default - Module1 module is selected. The default module resides locally in your user directory. If you want to copy the user-defined function to a Calc document: Choose Tools - Macros - Macro. In the Macro from field select soffice - Default - Module1 and click Edit. In the Basic-IDE, select the source of your user-defined function and copy it to the clipboard. Close the Basic-IDE. Choose Tools - Macros - Macro. In the Macro from field select (Name of the Calc document)- Default - Module1. Click Edit. Paste the clipboard contents in the Basic-IDE of the document. Applying a User-defined Function in $[officename] Calc Once you have defined the function VOL(a; b; c) in the Basic-IDE, you can apply it in exactly the same way as the built-in functions of $[officename] Calc. Open a $[officename] Calc document and enter numbers for the function parameters a, b, and c in cells. Set the cursor in another cell and enter the following: =VOL(A1;B1;C1) where A1, B1, and C1 correspond to the cells with the values for a, b, and c. The function is evaluated and you will see the result in the selected cell.
