usage: perl $0 [-tlqr] -d <days> [-p <port>]
* --localhost|l = use localhost HL7d (requires hl7d running)
* --query|q = output query to stdout
* --test|t = use remote test server IP::port
* --response|r = output remote HL7 server response
to use hl7d:
* config in /usr/local/hl7/hl7d.conf
* plugins /usr/local/hl7/plugins
* start hl7d: cd /usr/local/hl7d && sudo perl -T hl7d.pl --nodetach --debug
use $Net::HL7::NULL (double-quotation marks), or default (undef) for null fields
* use of default (undef) generates following warning: "Use of uninitialized value
$field in concatenation (.) or string at Net/HL7/Segment.pm line 187"
reason: my $field = $self->{FIELDS}->[$index];
$self->{FIELDS} = [
[0] "OBX",
...
[9] undef,
[10] undef,
[11] "F"
so index value of 9 or 10 will trigger warning - suppressed using Net::HL7::NULL
[9] ""
[10] ""
$Net::HL7::NULL set to 'true' if running under test mode (hl7d complains about undef fields)
