Module #02.01.01 : Individual structure creation

All PVT documentation can be found under PHIGS Validation Tests - Overview. You may also return to the hierarchical table of topics covered by the PVT. For an explanation of the format of the individual module documentation, please see section 2.5 of the User's Guide.


DESCRIPTION:  This module tests the various methods available to
create a new empty structure in the CSS.  Structure creation via
retrieval from an archive is tested under 03.03.  This module's
test cases directly use <inquire structure identifiers>, which is
tested explicitly in 02.01.
