Syntax Rules
- This clause is valid for input, output, update and literal fields.
- If the HIGHLIGHT clause is specified at group level, it applies to all suitable
subordinate elementary items.
General Rules
- If the FOREGROUND-COLOR clause is also specified, the HIGHLIGHT clause causes
the foreground colors to become brighter and lighter; for example on some
hardware, black can become grey and brown can become yellow. However, this
