Action Qualifiers

The time when an action associated to a step is executed depends on its action qualifier.GF_ProjectVX code implements the following action qualifiers.

Qualifier	Description	Meaning
N	Non-stored (null qualifier).	The action is executed as long as the step remains active.
P	Pulse.	The action is executed only once per step activation, regardless of the number of cycles the step remains active.

If a step has zero associated actions, then it is considered as having a WAIT function, that is, waiting for a successor transition condition to become true.
