That's fine, if the fields are contiguous. Aliasing to the group itself
means that it doesn't matter if they're contiguous or not.

Correct, just as in my example:
dim ItemNum(5):I2

Letter-number-paren at the start of a field name specifies it as part of an
associated field group. All groups with the same letter are related, so
that, for example, in @WLFI2 you can refer to any other I* field, and it
will mean the same instance as the I2 you just left. (In other words, if
you left the third I2, than a reference to I1 means the third I1, and I3
means the third I3, and so on. However, a reference to another letter
group, such as A2, you will get the first instance, regardless of whether
they are defined contiguously or not.)
