Query
Returns the error codes of all unread error messages in the internal error queue of the
Willtek 4400. The string returned will contain a maximum of 10 integers, separated
by commas.

errors”.
Example
:SYSTem:ERRor:CODE:ALL?

This means that there were two unread error messages in the error queue (the first
one indicating that there was a timeout on a FETCh command and the second one
meaning that the GPIB could not be initialized).

internal system message queue.

In this example, a RAPID! program performs some internal calculations and then
writes the result to the system message queue. This result is then read by the external
controller.
