FPE: Deleted Screenshot and cleaned up yj - checked functions; user-defined user-defined functions Basic IDE for user-defined functions IDE; Basic IDE programming;functions User-Defined Functions You can apply user-defined functions in $[officename] Calc in the following ways: You can define your own functions using the Basic-IDE. This method requires a basic knowledge of programming. You can program functions as add-ins. This method requires an advanced knowledge of programming. Defining A Function Using %PRODUCTNAME Basic Choose Tools - Macros - Organize Macros - %PRODUCTNAME Basic. 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 Function Using %PRODUCTNAME Basic", in the Macro dialog you clicked on Edit . As the default, in the Macro from field the My Macros - Standard - Module1 module is selected. The Standard library resides locally in your user directory. If you want to copy the user-defined function to a Calc document: Choose Tools - Macros - Organize Macros - %PRODUCTNAME Basic . In the Macro from field select My Macros - Standard - 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 - Organize Macros - %PRODUCTNAME Basic . In the Macro from field select (Name of the Calc document) - Standard - 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 the same way as the built-in functions of $[officename] Calc. Open a Calc document and enter numbers for the function parameters a, b, and c in cells A1, B1, and C1. Set the cursor in another cell and enter the following: =VOL(A1;B1;C1) The function is evaluated and you will see the result in the selected cell.
