Screenshots from the spell checker showing sample regular expression code and effect on free text. This figure combines two screen shots. Box A shows the interface that displays changes to free text done by regular expression. Box B shows examples of regular expression code that changes abbreviated month names to their full form. Note how several instances of the abbreviated month "Nov" are detected and converted to the full form "November".
