System-related commands

Commands:

SETCOLOR Set standard colors

SETECHO Set screen echo for key presses

SETFONT Set font for presentation of text pictures

SETOVERLAY Define a screen overlay for all subsequent trials

SETSYNC Sets synchronization mode for stimulus presentation

This group of session commands changes global system settings. The settings are active for the entire session until they will be changed by a new system command, either at the trial level or at the session level.

Most of the commands are also available as trial commands for changing system settings at the trial level. In this case see the trial command for a details description of command arguments.
