Got both responses.

Yikes! So the input routine is a general purpose string parser,
eh? I sort-of tried it, but only half-heartedly since I didn't think
it was valid. I don't think I actually tried the Parens "()"... just
did that for the posting. Better try again.
P.S.
In my half-hearted attempt to see if such a construct was possible,
I did get an error and therefore saw that Array is invalid for a
name...must be a key word. I changed to Arr() for my 'investigation'.

However, I am not actually doing that. The Array thing was only for
demo here and as a test vehicle for trying the construct. I did
rename starting at 0 for special reasons. I am putting the TextBox
value into a command string to send out the serial port. The
addresses into which the values go in the external device start at 0,
so subscripting is easier in the loop.
