322	dump_segment -as ELEMENT fails to parse ELEMENT with negative array index	Gary Dixon	Eric Swenson	"The problem is illustrated by the following dump_segment (ds) command:

{{{
ds 247|17240 -as ect_header.count""(-1)""
017240
dump_segment: Code 18. Parsing structure ect_header.count(-1).
}}}
 
The full ect_header structure is properly displayed, including the count(-1) array element.

Because dump_segment -as uses display services of the probe command, I suspect probe also has this difficulty.

Because the analyze_multics (azm) request display (d) uses the dump_segment_ display capabilities, I suspect azm display request also has this problem.
