The PERQ's original p-Code-like instruction set (called Q-Code) was optimized for Pascal (specifically, an extended PERQ Pascal). Q-Code instructions could be executed at a rate of up to 1 million instructions per second. This gave rise to the alternative definition of the PERQ name: Pascal Evaluation Real Quick. In fact it was generally more efficient to use Pascal than to attempt to create "assembly language" programs directly with Q-Code.
