Skywalker - Dictionary validation with BUFFER & BUFFER-FIELD
Two of the new objects in version 9 are BUFFER and
BUFFER-FIELD. The BUFFER object corresponds to
an underlying Progress buffer. The BUFFER-FIELD object
represents a field of the buffer. The VALIDATE-MESSAGE
and the VALIDATE-EXPRESSION attributes of the
BUFFER-FIELD allow the user to read or override the current
dictionary validation.
If a value is assigned to a BUFFER-FIELD object and that object
is not in a frame, the dictionary validation will not fire. This is
consistent with earlier versions of Progress. Dictionary validation
has always been a frame level validation.
