The getin database is quite sparse compared to the getout database.
Other than generating opening biggies, the getin database is used for substitution purposes.
For instance, suppose you have the following sequence:
Heads Wheel Thru, Swing Thru, Ah So, Grand 1/4 Thru, Recycle, Pass Thru, Barrel Of Fun, R.L.G.
It's basically an opening biggie that is too big. What you'd like to do is replace the junk at the beginning with a set of fewer calls.
To do this, edit the sequence [graphics mode], and use the <<,<,>,>> buttons so that part of the sequence is in the upper buffer, and part is in the lower (edit) buffer.
Heads Wheel Thru, Swing Thru, Ah So, Grand 1/4 Thru, Recycle,
Pass Thru Barrel Of Fun R.L.G.
Heads Box The Gnat, Split Right On 3,
Heads Box The Gnat, Split Right On 3, Pass Thru, Barrel Of Fun, R.L.G.
Tah-dah!
