SYSTem:ERRor?
This query returns the next error number followed by its corresponding error message string from the
remote programming error queue. The queue is a FIFO (first-in, first-out) buffer that stores errors as they
occur. As it is read, each error is removed from the queue. When all errors have been read, the query
returns 0,NO ERROR. If more errors are accumulated than the queue can hold, the last error in the queue
will be -350,TOO MANY ERRORS (see Appendix C for other error codes).
