Initial support for string type.

[jeinstei]

I think I found all the places this is used. I haven't been able to break it yet, at least.

[jeinstei]

Note that Verilog doesn't really support a string type natively. SystemVerilog does.

Here's what I'm getting from the standard:

unconstrained array types are allowed as long as the length can be determined by the actual/initializer. Otherwise it is necessary to have a constraint.

I did not found this sentence in IEEE Std 1076-1993 or IEEE Std 1364-2001. In the last one, the string support is depicted in section 2.6, page 10.

I'm find only allowing constrained strings-- but I'm finding Std 1076, 2000 Edition, section 13.7. I think you're correct except for some special, procedure cases. (ie procedure read_file)
