I’m using UTF-8 within the Yahoo! browser interface, but apparently it
doesn’t handle UTF-8 messages properly.

Please don’t hesitate to ask! I hadn’t set the -62 flag, because none
of those libraries’ documentation noted that setting flag -62 was a
requirement. (I haven’t finished reading the User’s Guide yet, so I
guess that I’m still crawling up the learning curve with knowing when
certain flags need to be set or cleared.)

That’s an excellent suggestion, and I’ve added it to my STARTUP program.

Once -62 was set, the key assignment worked; but when UTOOL tried to
run, it came back with an “Insufficient Memory” error. I thought that
that might be a side effect of the 2.10-7 ROM, so I installed the 2.09
ROM with its Equation Library and Periodic Table, reïnstalled my
STARTUP program and the three libraries, and retried the assignment;
but the same error occurred.

After some experimentation, I found that once I had created a 'units'
variable, UTOOL would execute. I must admit that I was surprised about
the insufficient memory error, since I haven’t filled up much memory yet.

Thanks for your wisdom!

Chris.
