CHANGE LOG

Wilhelm, April 27, 1982 4:05 PM

Barth, 7-May-82 10:58:25 PDT

Chen, 4/19/83:- modified itemType, operators, and expressionNode to support Max and Min operations.

Chen, 2/12/84:- modified to support oldArgVector.

Chen, June 12, 1984 10:05:25 am PDT, Cedarized.

McCreight, April 1, 1985 4:17:09 pm PST, added:

1. "data" fields in ModelRec and FunctionRec, modFuncBlk, ModelTableBlk, and FuncTableBlk;

2. hashModulus, HashKey, and ModelArgHash;

3. the handle and modFunc fields in ValueSeq;

4. modelArgs.

Chen, May 10, 1985 12:45:56 pm PDT, added ignorDvDtBelow to avoid concurrency problem using floating point software.

Chen, July 22, 1985 8:01:41 pm PDT, => Cedar6.0.
