Ok, this should be an easy one for you guys.  I'm sure it's something
simple (stupid) I'm over looking.  Why is it that MPLab will not program
the C84 beyond 512 bytes?  My program compiles fine but when I simulate it,
as soon as it hits step 0x01FF it jumps back to step 0.  There is 1K of
memory space right?  What am I missing?

duh ... thanks,

Yes C84 has 1K-Word memory.

16F83:
       ROM space : 512 x 14-Bit Words
       RAM space : 36 Bytes
16F84:
       ROM space : 1024 x 14-Bit Words
       RAM space : 68 Bytes
16C84:
       ROM space : 1024 x 14-Bit Words
       RAM space : 36 Bytes

Regards,
       Philippe.

I noticed this to with the latest version of MPLAB (3.12.14).  According to
MPLAB, the 16C84 only seems to have 512 Instructions.

The other problems I noticed were:

1.  Sometimes on pulling up a project, the right side of the Stopwatch is
cut off (to the edge of the window beside it - even if it doesn't show up
(see the next problem)).

2.  Sometimes on bringing up a project, if a custom watch window has been
created for it, the watch window didn't come up.

I didn't report these problems earlier because I am only running 3.12.14 on
a  laptop running Windows 3.11 (that I'm having some hard drive problems)
and I wasn't sure the problems were in MPLAB, or in the laptop.

Oh - the 16 bit variable display now available for the Watch Windows is
really fantastic!
