I hope someone knows a faster way :-)
I'll read the rest of the email carefully and (hopefully) have more
comments later.
But for now, I'll try this one part.
I don't know a way to do this much faster. You'd get a small (perhaps
very small) improvement by replacing the central line by
put 1 into TestArray[rLine]
but (without testing it), I suspect it will be a small change.
However, if you can change your input lines slightly, you can do
something that should be better. If these are permutations that you are
generating, then as you generate each one, you might be able to add an
extra character onto each line (let's say, a colon ":"). Then your data
would look like
123:
125:
152:
231:
etc.
With this input, you could do
split pData by CR and ":"
combine pData by CR and ":"
and all your duplicates have disappeared.
It might be even faster to do
split pData by CR and ":"
put the keys of pData into pData
and that would remove those extra ":"s for you at the same time.
