RE: New RPG Redbook (was Sub Files).(and quick sort)

That was why I wrote the demo code that way.  I was timing it against SORTA.

For a one time call it's a lot easier to pass the procedures as parameters.
If I remember from when I was playing with it, (last year) the difference
between passing variables vs. executing the procedure calls was in
milliseconds for 100 iterations.  It's scary how long(short) things actually
take.  A lot of the things I learned about optimizing code (which are still
applicable, in a way) came from when I was in school using 286s and low end
386s.  A few months ago I wrote a C program for the first time in 7 or 8
years and discovered that using a register integer for a loop control
variable made virtually no difference in a 25 iteration loop that executed
10,000 times.   

It would be a pretty cool compiler trick if it could analyze a loop and find
the procedure calls that were returning the same value every time and create
temporary variables for the return value.
