--- OBJECTIVE:
--- Check that representation items may contain nonstatic expressions
--- in the case that each expression in the representation item is a
--- name that statically denotes a constant declared before the entity.
---
---
--- TEST DESCRIPTION:
--- For each of the specific items in the objective, this test checks
--- an example of each of the categories of representation specification
--- that are applicable to that objective, to wit:
--- address clause ....................... Expressions need not be static
--- alignment clause ..................... Expressions must be static
--- bit order clause ..................... Not tested
--- component size clause ................ Expressions must be static
--- enumeration representation clause .... Expressions must be static
--- external tag clause .................. Expressions must be static
--- Import, Export and Convention pragmas Not tested
--- input clause ......................... Not tested
--- output clause ........................ Not tested
--- Pack pragma .......................... Not tested
--- read clause .......................... Not tested
--- record representation clause ......... Expressions must be static
--- size clause .......................... Expressions must be static
--- small clause ......................... Expressions must be static
--- storage pool clause .................. Not tested
--- storage size clause .................. Expressions must be static
--- write clause ......................... Not tested
---
--- APPLICABILITY CRITERIA:
--- All implementations must attempt to compile this test.
---
--- For implementations validating against Systems Programming Annex (C):
--- this test must execute.
---
--- For implementations not validating against Annex C:
--- if this test compiles without error messages at compilation,
--- it must bind and execute.
---
--- PASS/FAIL CRITERIA:
--- For implementations validating against Systems Programming Annex (C):
--- this test must execute, report PASSED, and complete normally,
--- otherwise the test FAILS
---
--- For implementations not validating against Annex C:
--- PASSING behavior is:
--- this test executes, reports PASSED, and completes normally
--- or
--- this test executes and reports NOT_APPLICABLE
--- or
--- this test produces at least one error message at compilation, and
--- the error message is associated with one of the items marked:
--- -- N/A => ERROR.
---
--- All other behaviors are FAILING.

--- CHANGE HISTORY:
--- 11 JUL 95 SAIC Initial version
--- 10 MAR 97 PWB.CTA Made Nonstatic_Entity nonstatic; changed
--- Tenths'Small from 1.0/32.0 to 1.0/10.0,
--- as expected by the later check; improved
--- internal documentation.
--- 16 FEB 98 EDS Modified test documentation.
--- 24 NOV 98 RLB Changed Tenths'Small to 1.0/32.0, as this is
--- necessary so that all implementations can
--- process this test. (3.5.9(21) means non-binary
--- smalls are optional.)
--- 11 MAR 99 RLB Merged versions. Most EDS changes removed (as
--- they made the test less applicable than the ACAA
--- version).
