sections:

 Section 1

error/event queue When the command parser detects a syntax error or data range

error, it places an error message describing the error in the Error/Event queue.

Bit 2 of the Status Byte Register is set to indicate that this queue is not empty.

Bit 5 of the Standard Event Status Register (the Command Error bit) is set if the

parser detects a syntax error. Bit 4 of the Standard Event Status register (the

Execution Error bit) is set if the parser detects a numeric argument that is out of

range. When a SYSTem:ERRor? query is received, an error message is dequeued

from the Error/Event queue and placed in the Output queue.
