Flow functions

Use Flow functions to specify a value for each of the flow variables defined for a flow, and additionally, to alter an already specified value for a flow variable.

Flow variables act as an alternative means to pass information throughout a flow instance without requiring the use of data links.

Flow variables are name value pairs that persist until the flow instance completes execution. Flow variables are case-sensitive. Flow variables are also instance-specific. Instance-specific means that no two flow-instances that are running simultaneously can share the same set of variables.

Flow functions return the output in UTF-8 character encoding format. The flow variable name and value are converted to UTF-8 character encoding before a flow function is executed.
