- Hello,
-
- I've been working on an implementation of bc and have been
- using the POSIX draft as a definition of the language. In
- working on the program, I have found several problems with
- the draft. I have P1003.2/D11 and any line number references
- are from that draft. The following are what I consider to be
- problems. If I am wrong, please help me understand what the
- committee intended.
-
- 1) The character '-' "shall" be recognized as both the token
- ADD_OP and the token '-'.
- lines: 1587, 1670, 1737, 1738, 1749-1751
-
- 2) Lines 1642-1644 are
- parameter_list : LETTER
- | define_list ',' LETTER
- I presume it should be
- parameter_list : LETTER
- | parameter_list ',' LETTER
-
- 3) Lines 1836-1838 state "A whole array passed as an argument
- shall be specified by the array name followed by empty square
- brackets."
- a) I find no provision in the grammar in the definition of the
- parameter list define a parameter as an array. (See lines
- 1642-1644.)
- b) No provision is made in the grammar for the specification of
- an array in the actual function call. (See 1657-1659.)
-
-
- I am interested in knowing if these have been noticed before and if
- there are changes to the draft.
