You can change the definition of a user-defined function at any time. You change the processing performed by the function by modifying the statements in the Script view. You can also change the return type, argument list, or access level for a function.
To change a function's return type, arguments,
or access level:
Do one of the following:
In the Function painter, open the global function
Open the object that contains the object-level function you want to edit and select the function from the Function list
Make the changes you want in the Prototype window.
If the Prototype window is hidden, click the toggle button to display it.
Select File>Save from the menu bar.
To change a function’s name:
If desired, modify the function’s return type, arguments, or access level as described in the previous procedure.
Do one of the following:
In the Function painter, select File>Save As from the menu bar and enter a name
In the Script view, enter a new name in the Function Name box
When you tab off the box, the new function name displays in the Function List view.
You can change a user-defined function's arguments at any time using the pop-up menu in the Prototype window.
Add an argument by selecting the Add Parameter menu item. Boxes for defining the new argument display below the last argument in the list.
Insert an argument by moving the pointer to the argument before which you want to insert the new argument and selecting the Insert Parameter menu item. Boxes for defining the new argument display above the selected argument.
Delete an argument by selecting it and clicking the Delete Parameter menu item.
To change the position of an argument
To change the position of an argument, delete the argument
and insert it as a new argument in the correct position.
Changing arguments and the return type of a function affects scripts and other functions that call that function. You should recompile any script in which the function is used. This guarantees that the scripts and functions work correctly during execution.
PocketBuilder provides browsing facilities to help you find where you have referenced your functions. In the System Tree or Library painter, select a target, library, or object and select Search from the pop-up menu. You can also search multiple entries in the Library painter.
To determine which functions and scripts call
a user-defined function:
Open the Library painter.
In a List view, select all the entries you want to search for references to the user-defined function.
Select Entry>Search from the menu bar.
The Search Library Entries dialog box displays.
Specify the user-defined function as the search text and specify the types of components you want to search.
Click OK.
PocketBuilder displays all specified components that reference the function in the Output window. You can double-click a listed component to open the appropriate painter.
For more about browsing library entities, see “Searching targets, libraries, and objects”.
