GRSYS (Grid System) Attribute
This attribute specifies the grid system to use during a search for the ‘nearest’ GRIDLN element, when generating the output from positional codewords used by elements whose POSFOR attribute has a value of 2 (Ship Reference System). If the POSFOR attribute has a different value, the GRSYS attribute is ignored. If the search for the GRIDLN element fails (no suitable grid lines), the XYZ output is generated instead.
The value of the attribute will cascade down from the DEPT or LIBY element to their child elements when they are created.
Example:
GRSYS NULREF
tells DRAW to use all available grid systems with the default orientation (0, 0, 0) and the purpose SHIP when searching for the nearest GRIDLN element
GRSYS /RO-RO
tells DRAW to use the grid system /RO-RO exclusively when searching for the nearest GRIDLN element.
