Re: Multi Dimensional Array

["Scott Klement" <infosys@xxxxxxxxxxxx>]

Rajeev,

       Maybe I don't understand what you're trying to do, but I'm
completely missing what you're saying about the "trailing blank"
characters.  Where did they come from?

You seem to be viewing an array as a collection of records, and its
not... its (in this example) 6000 byte area of memory, thats divided
(only by our program logic) into 60-byte chunks by doing some simple
math.

You don't want/need delimiters because the "records" that you're
referring to are actually FIXED LENGTH.  Therefore, you know that
the first record ends in position 60 and the next starts in position
61.

In an array, each discrete unit is independent of the others.
In the example I showed you, each element of the array is alphanumeric
and is one character long.

You can't assign 'New Stringbbbbb' to it because thats MORE THAN ONE
character long.

If you're not looking for a two-dimensional array (an array that
has two dimensions instead of one) but are rather looking for a way
to load multiple records into memory, you'd be better off using a
multiple occurrance data structure!

Maybe if you explained a bit more about what you're doing, and why,
I'd be able to give you an answer that'd make more sense...
