IBISCHK6 Code Cleanup:

- Bob showed an email from Curtis Clark.
- Bob: RCS revision data lines in files like mdl.c have not been updated.
- Mike: That could be deceptive.
- Bob: Curtis has a script to remove them.
  - I will ask Atul about this.

- Bob: We would have about $7,900 available for parser work.
  - There also might be one more parser sales coming up.
  - Interconnect and backchannel work might add to the cost.


AMI string parsing rules, related to recent E4662 "bug":

- Bob showed the bug testcase.
- Mike: The parser works like a shell in the way it handles AMI double quotes.
  - Characters adjoining a quoted string become part of the string.
- Bob: That syntax is in error.
- Mike: I think IBIS is about 90% clear on that.
- Bob made AMI changes and ran IBISCHK to prove that it allows spaces in strings.

- Bob showed the requirements for String in IBIS.
- Mike: It violates the last sentence because a quote is in the middle.
- Bob: This mainly violates the first sentence, that it must be enclosed in quotes.
- Mike: Would it be legal to have no space between two quoted strings?
- Bob tried putting a pair of quotes in the middle of a String.
  - That passed IBISCHK.

- Mike: We should file a bug for this.
  - A String should begin and end with a quote and not contain quotes.
  - Also List should require some space between Strings.
  - That would apply to Table too.
- Bob: This will be bug 159

AR: Mike draft String parsing bug report and send to Bob for review.

Meeting ended: 12:06
