186 PMAC On-Line Command Specification

&{constant}

Function

Address a coordinate system.

Scope

Global

Syntax

&{constant}

where:

• {constant} is an integer from 1 to 8, representing the number of the coordinate

system to be addressed

Remarks

This command makes the coordinate system specified by {constant} the addressed

coordinate system (the one on which on-line coordinate-system commands will act). The

addressing is modal, so all further coordinate-system-specific commands will affect this

coordinate system until a different coordinate system is addressed. At power-up/reset,

Coordinate System 1 is addressed.

Note:

A different coordinate system may simultaneously be hardware

selected from the control panel port for coordinate-system-specific

control panel inputs, and that different coordinate systems may be

addressed from programs within PMAC for COMMAND statements.

If the control-panel inputs are disabled by I2=1, the host-addressed coordinate system also

controls the indicator lines for the in-position, warning-following-error, and fatal-following-

error functions. These indicator lines connect to both control-panel port outputs (all PMAC

versions), and to the interrupt controller (PMAC-PC, PMAC-Lite, PMAC-STD). (If I2=0,

the hardware-selected coordinate system controls these lines.)
