  FIELDBLOCK()      Does not return NIL for invalid cFieldName

  Clipper Version  1.29 dtd 04/15/91.

  Problem Statement

  The NG erroneously states that FIELDBLOCK will return NIL if <cFieldName>
  is not in the current work area. FIELDBLOCK will return a code block,
  which, when evaluated, will cause a runtime error.

  Work Around(s)

   Verify fields, before using FIELDBLOCK.
