Assume a hull form offset table your want to store in a parameter HullForm$ because parameter HullForm$ because it is needed as part of an input file for hypothetical software to calculate e.g. hydrostatic properties.

HullForm$ is determined by means of a relation:

...

During calculation the system will look for this object in the current solution. If not found, it will look in the Dataset of the project and if it is not found in the project either, it will look in the Dataset of the knowledge base.

The line "HullForm$" "" in the script tells the system that at least a DETERMINED value of HullForm$ should be available to allow selection of a case. This means, that the result of the selection cannot be empty values for HullForm$for HullForm$, therefor Quaestor will pre-filter all these cases out of the total dataset. The selection of HULLDATA# will contain all other DETERMINEDvalues available in the selected record. Also SHIPTYPE$, PROJECT$ and CONDITION$ should be DETERMINED (thus available) to allow a selection.
