deletedelete chunk of container delete [menuItem of] menu delete [menuItem from] menu delete { button | field | part }
The delete command removes text from a container, menu items from a menu, menus from the menu bar, and buttons or fields from the current card or background. When you use the form delete part, deleteButton or deleteField is sent to the object that's being deleted. You can't use this command to delete a part anywhere except on the current card. Note: Using delete to delete a line is not the same as putting empty into the line: delete removes the final return character as well as the text, while putting empty into the line just removes the text. Examplesdelete item 3 of line 1 of field "Expenses" delete line 5 of button "Text Holder" put " this has a space" into theText delete character 1 of theText delete menu "File" delete menu 2 delete second menu delete menuItem "New" from menu "File" delete menuItem 2 from menu 2 delete second menuItem from second menu delete button 1 delete last card field delete background button id 1234 delete last background part
