structures

[jbv]

IIRC in C structures are composed of elements of
various natures (variables, arrays, strings...) and
AFAIK such a concept doesn't exist in Transcript.

As for your example, why don't you simply use
a 3 dimension array ?
In which way using a struct. would be cleaner than
an array ?
