getting count of array with non-integer index

[Jan Schenkel]

Hi Trevor,

As you haven't gotten a reply yet on the list, I
figured I'd have a stab at it :-)

First of all, you are setting up the arrays correctly,
so no worries there.

To answer your second question, you have a few
options, depending on the circumstances.

1) If the second dimension is fixed (always NN
elements), you can suffice by saying:
  put (the number of lines of the keys of tArray / NN)

2) If however NN is variable, you can get it with the
following trick:
  put the keys of tArray into tKeys
  split tKeys using return and comma
  put the number of lines of the keys of tKeys

I know it looks convoluted, but it works, even if the
second dimension varies.

Best regards,

Jan Schenkel.
