@-Command Overview

Several variations of these commands are often possible, since K for a constant, R for an R-parameter or P for an R-parameter used as a pointer can be used for parameters. For example, the notation K/R/Pn should be understood to mean "either a number or an R-parameter or a pointer".

The following @-commands are available:

Machine data

Access to the following machine data is supported:

Byte	Bit	Action
5003	5	0: IJK words specify the distance between the center of the circle and the starting point. 1: IJK are absolute data giving the center of the circle.
