This function allows you to prepend text to the start of one or more fields, a named variable or each field specified in a list in a named variable. Which fields or text strings you are processing is discussed in Statement Source/Target Determination. The same topic describes the ability to treat each field or named variable as a list where each list component will be processed.
If both a string and a field are specified, the results will be: string - field contents - original contents.
When in stepwise execution mode and you're prepending text to a named variable, the function is only performed once.
The supplied strings may contain any of the escape sequences described in Escape Sequences.
The optional text field can be displayed in a multi-line editor by clicking on the control to the right of the field. \n sequences are changed to newline characters when displayed and changed back to \n sequences after editing.
