Group Validation
A group is valid if the syntax is valid and all of its components are valid. A group is
validated component-by-component. A component is valid if its type is valid, its
component range is valid, and, if the component has a rule, the rule evaluates to
TRUE.
Note When a component rule is evaluated, any invalid data used in a component rule is
evaluated with a value of NONE.
After all of the components of a group have been found, a message in the trace
file indicates that the group itself was found.
For example, the components of Row are Name and Phone# and the data for
Row is:
Nicole,352-2929
To find the object Row in the trace file, first the components of Row are found.
The trace file contains a message for Name, then one for Phone#, and one for
Row.
Shown below are the trace messages that correspond to the validation of a Row
data object:
Valid Card Objects
If all of the objects that make up a card data object are found, the card object is
valid. There is a trace message indicating this status. For example, if the data
object for card 1 was valid, the trace message INPUT 1 was valid
appears in the
trace file. The message for a card object appears after all of the messages for the
objects within that card.
