Multidimensional array issue

[Ralph DiMola]

If “item” is among the lines of the keys of tDataA and tDataA [“item”] is empty then --it's an array key with an empty value.

The trouble is, if tDataA [“item”] variable does not exist, that is it is not an array, you will still get empty.

When I want to determine whether or not an array element contains non-whitespace, I usually say:

    if word 1 of tDataA["item"] is empty then ... (or is NOT empty)

Just another option.
