More questions about the FreePascal Language Reference (version 3.2.0), part

34. Are macpas LEAVE and CYCLE statements undocumented ?
Yes.
35. Are macpas ellipsis (...) parameters undocumented ?
Yes.
36. Is the macpas RETURN statement undocumented ?
Yes.
37. Shouldn't the macpas "mwpascal" modifier be added to ?
call-modifiers = "register" | "cdecl" | "pascal" | "stdcall" |
"safecall" | "inline" | "mwpascal" .
call-modifiers = "cdecl" | "inline" | "local" | "nostackframe" |
"overload" | "pascal" | "register" | "safecall" | "saveregisters" |
"softfloat" | "stdcall" | "varargs" | "mwpascal".
Yes. There are even more.
38. Is a <constref-parameter> rule missing ?
constref-parameter = "CONSTREF" identifier-list [ ":" [ "ARRAY" "OF"
] type-identifier ] .
where
parameter-declaration = value-parameter | variable-parameter |
out-parameter | constant-parameter | out-parameter | constref-parameter .
Yes.
39. Section 16.7 defines a rule <library> and a rule <exports-clause>
library = library-header ";" [ uses-clause ] block "." .
exports-clause = "exports" exports-list ";" .
The exports-clause rule however doesn't seem to be referenced anywhere in the
syntax, so it may have to be added to the <library> rule ?
To the library rule, but also to the unit rule, because it can also appear
in a unit...
40. < recordoperator-definition> = <record-operator-definition> ?
Yes.
41. Is it correct that <operator-definition> is referenced only in the record
<component-list> rule ? I would expect something like an
<operator-declaration-part> in various declaration rules.
To the best of my knowledge, only records support operator definitions.
The 'operator' chapter handles 'global' operators which are at the level of
global functions/procedures.
Michael.
