27 -- WIDTH PARAMETER IS NEGATIVE, IF THE WIDTH PARAMETER IS

31 -- TYPE.
|
|
|
32
|
|
|
33 -- HISTORY:
|
|
|
34 -- SPS 10/04/82
|
|
|
35 -- DWC 09/09/87 ADDED CASES FOR WIDTH BEING GREATER THAN
|
|
|
36 -- FIELD'LAST AND THE VALUE BEING READ IS OUT
|
|
|
37 -- OF ITEM'S RANGE BUT WITHIN INSTANTIATED
|
|
|
38 -- RANGE.
|
|
|
39 -- JRL 06/07/96 Added call to Ident_Int in expressions involving
|
|
|
40 -- Field'Last, to make the expressions non-static and
|
|
|
41 -- prevent compile-time rejection.
