Summary0005944: Misleading sentence for lengthof for arrays.
DescriptionThe current text, regarding the lengthof arrays is:
"For record of, set of, and array, the value to be returned is the sequential number of the last initialized element: in case of record of and set of the index of that element plus 1. In case of arrays, lengthof should return the index of that last element minus the index of the first element plus 1.
The length of a fixed length record of, set of, or array value will always be the fixed length according to the type definition."

Arrays are equivalent to fixed-length record ofs, thus the sentence "In case of arrays..." is simply wrong and contradicts to the next sentence ("The length of a fixed length record of, set of, or array value will always be the fixed length according to the type definition.").

Arrays are always of fixed length. Therefore each instance of an array definition (like instances of fixed-length record/set of types) shall have exactly the length specified in the definition. The text shall be changed to:
"For non-fixed length record of and set of, the value to be returned is the sequential number of the last initialized element: the index of that element plus 1.
The length of a fixed length record of, set of and arrays shall always be the fixed length according to their types: in case of record of and set of the size specified by the length restriction of the type definition, in case of arrays it shall be the upper index minus the lower index plus 1."

Agreed. But I would grammatically re-formulate it to:

"The length of a fixed length record of, set of or array shall always be the fixed length according to its type ..."

has to be discussed as different tools give different results. Therefore we need more detailed investigation.

STF discussion 28/11: formulate the resolution text. Take into account the minimum length acc. to the lenght restriction; fixed length is a special case of this.
