Cache functions

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

Cache variables act as an means to process information throughout a flow instance without requiring the use of data links.

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