Improving Performance
M-2 Issue 4 September 1995
Lookahead Interflow
All looping examples in this appendix use only loops within a single vector. It is
important to also be aware of looping to other vectors through the use of vector
chaining. The same principles can be extrapolated from the looping examples.
Creating a flow diagram is often helpful for identifying looping errors.
In addition to the example vectors, tables rating the relative performance costs of
specific vector commands are also included.
NOTE:
Remember to test vectors for performance in addition to call flow.
