The tools caget caput and camonitor are really designed for human consumption.
If you're writing scripts that make more than a few calls (especially if they
are long-running or involve looping) you should consider switching to a
scripting language that has a direct interface to the CA library. There are
several Python interfaces available, and a Perl library comes with Base
R3.14.10 (look at base/html/CA.html for documentation). These will all allow
you to fetch arrays the way you want them, and they can help reduce the load
on your IOCs when compared with scripts that repeatedly run the command-line
tools.
