Subject: Bug in command line shell caget

The shell command "caget" will core dump as follows:

chiron 578: caget S:bpm32:SlowBh:xBF
Segmentation fault (core dumped)
chiron 579: notes sw-bugs

when accessing float arrays > 4000 and double arrays > 2000.

Inspection of the code shows these limits are hard coded.  Real channel access
allows somewhat greater limits, 4089 for floats I believe.  But that's beside
the point, caget should not core dump.
