Data Types

String

• Strings can be represented by the value of a variable or by an expression like "this is a string" or 'this is a string'.
• Note that a string that is not the value of a variable requires to be quoted: either single quotes or double quotes can be used.
• If a single quoted string contains a single quote than this has to be escaped with a backslash, e.g. 'De Morgan\'s law'.
• If a double quoted string contains a double quote than this has to be escaped with a backslash too.
•  An empty string has to be specified with double quotes like this: "".

• Technically this use case is not too different from the checking return values use case described above. However, the focus is not on a specific job but on specific values of variables.
• Note that order variables can be modified by users when adding an order. The above example therefore checks an order variable to decide which job a workflow is to be started for.
• Note also that the same check can be performed for any step in a workflow.
