- It also had a bug with the optimizer that would cause it to compile and
- run fine, but it wouldn't update certain varibles within an decrement loop...
- it would calculate the value of the variable properly the first time through
- the loop, but then after the loop terminated, the variable would still have
- the initial value...worked fine w/o optimizer and fine under xlf 2.2...
- IBM sent us a bug fix that fixed it...hopefully your version will already
- have the bug fix in it...
