Purpose:
Evaluates if a string is empty. If it is empty, "True� will be the return value, otherwise "False�. Useful, for example, to determine if the field "ADDRESS� is empty, and if it is, in combination with the IF-THEN-ELSE condition cond(), either print the contents of the field "ADDRESS� or "POBOX�.
The third parameter allows the removal of leading and trailing spaces. If this is evaluated as "True�, a string consisting only of multiple spaces will be recognized as empty.
Parameter:
String
Boolean (optional)
Return value:
Boolean
Example:
Empty("xyz") Result: False
Empty("") Result: True
