Yes, access to the HISTOGRAM command is bothering me, too.
I was hoping to finesse it, since simple access was all I
required for my application, but I realized I probably
wouldn't be able to get away with this for long.

We really need multiple _EXTRA keywords, or targeted keywords,
or something. There are three different COMMANDS I want access
to in this program, and having to resort to one _EXTRA is
giving me heartburn. :-(

I some ideas, but I'm working on getting a failed hard drive
back in business this morning....

Cheers,

David
