Message: [QUOTE="DJ Stunks, post: 4861910"] Well, I think responder #1 missed what I was going for and responder #2 appears to be off his meds. However, I tried Tie::IxHash and it works quite well for me. It's immediately clear what the values are for the various API parameters and it skips the necessity of the @order array and the associated hash slice. The only concern is that maintainers must realize the order in the hash is critical. Code below for the curious. Thanks, Jake #/usr/bin/perl use strict; use warnings; use Tie::IxHash; tie (my %parms, 'Tie::IxHash'); #API syntax: my_API_call (<this_parameter>,<that_parameter>,<extra_parameter>) %parms = ( this_parameter => 'some value', that_parameter => 'another value', extra_parameter => 'a third value', ); my $stringified_API_call = 'my_API_call(' . join(',', values %parms) . ')'; print "call it: $stringified_API_call\n"; __END__ [/QUOTE]
