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
