You're right that the on-line help is a bit vague on this point. You can
string multiple statements as long as they each end with a semicolon, with a
comma separating the compound statement from the iteration specification.

  {x, 1, 5}]

Alternately, you can enclose the compound statement in braces, with a comma
again indicating the iterator as here

  {x, 1, 5}]

Hope that helps.


PS: I can't tell you how much I resent no-spam manoevers that presume your
time is more valuable than mine :)
