Query Hatching Rulesets and Styles

The querying facilities are similar to those provided for RRULs. Thus at a HRUL:

Q DESCription

outputs a description for that HRUL with the format:

USE hstyl FOR criteria

At a HRST:

Q DESCription

outputs an ordered list of descriptions ‑ one for each of its HRULs.

At a VIEW:

Q HRSF DESCription

outputs an ordered list of descriptions starting with those of the HRULs it owns & then those of the HRST it references.

At a VIEW or HRST:

Q HSTYF FOR design-id

returns the HRUL that is relevant for the specified design item. The <design-id> can be repeated if the HRULs for a list of design items are required.
