You got a bug. If non-zero elements are moved, then you must assign a zero to where those elements were moved from or the interior start loop will not know when to stop. It would in effect move until it reached the last non zero item in the list and then write that value repeatedly whenever a zero was encountered.

start would continue to increment, yes, but it would not do any more writing, since you have
If start < finish Then
a(start) = a(finish)

so the incrementing is harmless.

Because the loop "does" know where to stop, you don't need the start < finish checks in the interior loops.

As Larry pointed out, you do to avoid running off the end. Once you put the test in, then start will never increment past finish, so there is never any concern for what lies higher up than finish. Ergo, no setting to 0 is needed.


Larry is like "a black hole". Even the most obscure details can't escape him. A sharp mind.
