SYMPTOM(s):
A character concatenation expression returns an unknown value.
The expression is similar to the following:
cResult = cField1 + cField2 + ... + cFieldn.
CAUSE:
One or more of the items in the expression is unknown ( i.e. equals to ?).
FIX:
This is expected behavior. The result of any operation involving one or more unknown items is unknown. Ensure that every item is not unknown before concatenating it to the result string.
