determining array lengths

[Jan Schenkel]

Hi Brad,

I looked into this a while ago. My solution was:

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.

Hope this helped,

Jan Schenkel.
