( #3333=superdoc: print w/ replies, xml ) Need Help??
I have a program which processes data and produces outputs. I have concepts like Track and Track_Group, and templates for converting them into the chain configurations used by a sound engine to mix, route and process audio signals.

Right now all my code (except the GUI widgets part) is procedural, using hashes and arrays to store data. I am implementing two operating modes:

* A Tk GUI event loop

* A command-line parse-and-execute loop

My code, already close to 4k lines, is sprouting such conditionals as:

&refresh_track_display if $gui;
At the moment I have only about ten of these statements. Should I think about trying to eliminate them? What are my alternatives?

This is a concern as I am considering an incremental move over to a OO style and higher levels of abstraction. How might OO design or some other abstraction help me support this dual-interface ability?
