Data Form Design Restrictions

Restrictions on Field Pictures

You must observe certain restrictions on field picture strings when designing a data form to be used with the Vermont Views clipboard interface. All data entry field pictures must (1) contain no protected characters and (2) be pure, that is, consist of picture control characters that allow the same type of character entries. This means that field pictures:

• nCannot contain protected characters, including a hard decimal separator or 'E'.
  
  
• nCannot contain mixtures of alphabetic (X, A, Z, *, !) and numeric (U, 9, #, @) picture control characters.
  
  
• nCannot contain mixtures of Xs, As, and Zs. (The picture control characters ! and *, which convert letters to uppercase or lowercase, do not destroy the purity of either a string of Xs, Zs, or As.)
  
  
• nCannot contain mixtures of Us, 9s, and #s.

These restrictions are necessary to provide users the full editing capabilites expected with clipboard edit actions. In addition, the restrictions limit the potential for characters to be pasted into positions where they might not be valid.
