RE: strings, string variables, string parameters

Geoffrey,

Thanks for pointing this out to me.  Re-reading sections 2.6.1
and 3.2 of the v2.2 LRM, it just dawned on me that parameters
are constants which is different from variables.  I believe this
justifies my expectations with the `define even more, which I
will explain in another message.

Thanks,

Arpad

Arpad -
A "string variable" is a different animal entirely, see 2.6.1
of the 2.2 LRM (string variable declaration).

String parameters are new in the 2.2 LRM; I think they're not
in 1364, we took them from SystemVerilog.

Probably many of the places where a string is used in the LRM,
one should be allowed to use a string parameter.
