Re: IBIS standard inconsistency

Stephen,

My reading of the spec suggests you are free to use any of these styles.....

| 1) The content of the files is case sensitive, except for reserved
| words and keywords.

| 6) Keywords must be enclosed in square brackets, [], and must start in
| column 1 of the line. No space or tab is allowed immediately after the
| opening bracket '[' or immediately before the closing bracket ']'. If
| used, only one space (' ') or underscore ('_') character separates the
| parts of a multi-word keyword.

Have you experimented with the golden parser to see what it will accept?
