Rules: You cannot use two numeric literal fields. For example,
♦ If
buffer-field1
contains a numeric literal,
buffer-field2
must contain a
field.
♦ If
buffer-field2
contains a numeric literal,
buffer-field1
must contain a
field.
When you use a numeric literal, the script places the result in the field that is not a
numeric literal.
Optional Fields Invalid and valid labels are discussed in “Script Flow" at the beginning of this
chapter.
