I'm compiling with -2008.

Thanks

I'm using std.textio.all.
I'll give the other library a try, but sample_val is an integer,
so I didn't think I'd have to mess with std_logic stuff.

Thanks

Probably my problem is that sample_val is an integer.
How to I print an integer as hex?

Thanks

Thanks. I'll try that.
It's my first time using textio, and I just assumed
some formatting control was provided somewhere,
but that I was too dumb to find it.

It was in the original post, if you missed it:
std_logic_vector(to_unsigned(sample_val, <length>))

make sure <length> is multiple of 4 if you intend to use it with hwrite.
