Those implementing new architectures (hardware or software) should study this list carefully, since the adoption of these functions would give the programmer vitally needed control over previously hidden operations.

In most cases the computer system will perform these mnemonic operations without you requesting them. However, all of you that do programming may need to use at least one of the following daffy mnemonic commands:" Steve Summit tektronix!tekmdp!stevesu
