## Prepend

This function allows you to prepend text to the end of selected fields or a named variable. You may also optionally prepend the contents of a specified field. If both a string and a field are specified, the string is prepended before the field 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.
