Derek:
I agree. But I'd call this "convenient", not "necessary".
Regards.

source code structured in such a manner that it reflects the architecture of
the application. That's a fancy way of saying the I'd like to have related
routines physically close to each other in the source code.

around the source files so that they can used - this is one of the reasns
why Win32lib is such a dog's breakfast. For example, I sometimes will change
a routine so that it now calls another routine, only to find that the
routine I'm now calling is further down the in the source file. So I must
rearrange the code to accommodate RDS's philosophy. And in doing so, I might
suddenly find that I need to more more than one (often unrelated) routine to
get it 'just right'. In fact, I've gotten so sick and tired of doing this
that now I resort to routine_id() calls instead of rearranging source code.
Call me lazy, but it is not effective coding practice (IMNSHO) to
continually be concerned with juggling the physical layout of source code.

layouts. I can group my routines in a logical manner and not worry about
where in the source code a routine is physically coded in order for me to
use it.
