Supplying a Literal Value

To supply a literal value for the update text string, use the form ‘literal’, where the following rules apply to the literal value:

• A single quote ( ' ) is required around the string that is a fixed value. Any single quote ( ' ) embedded in the string must be escaped by an additional single quote ( ' ' )

• Numbers are surrounded with single quotes ( ' ) for ease and clarity of processing.

• The following operations may be used: +, -, /, *

• Grouping within equations with the and operator is allowed.
