In languages with static typing, type names can (and IMO should)
be used to indicate the purpose of identifiers declared with
those type names.  Redundantly adding type or purpose information
to an identifier name is, well, redundant.

These comments don't apply to the orginal context (BCPL) of
Hungarian notation, since BCPL doesn't have any notion of
static typing.

Hungarian notation predates Microsoft as a company, let alone
Microsoft word.  It may be the case the Hungarian notation was
used to indicate a coordinate value (as opposed to, say, a string
length), but it was certainly not initially in any Microsoft
product.
