'Pic Start Plus'

Hi,
I'm developing code for the 16C74 and am programming the chip using
the PicStart Plus programmer.
My program at present is about 500 lines, when I program the device
the programmer counts up to 0FBE which would say that I don't have a
lot of program memory left. But, when I look in the Program memory
window it goes up to 014A. Everything after this is blank .i.e 3FFF.
Can someone tell me what my real program size is.
Thanks.
Ross.

HI!, you dont have any problem, the programer counts the empty space
too!

First: The PicStart+ writes its _whole_ memory to the PIC.  Even blank data
(0xff) will be written.  This accounts for the up-count to end-of-memory.

Second: Because you can create multiple-origin data (org xxxx directive)
your
code can be fragmented in memory.  You _could_ have some bytes left, but
scattered here-and-there and therefore unusable.

And now: the Answer :-)
Look in a file with the extention .LST .  At the end of the file is a block
with
dots and X-es called a 'Memory usage map' . Here you will find what area's
of memory are used.  Be carefull, as is said below this block, Unused
memory is not shown !

Assuming you are using MPlabs to write your code if you open the .lst file
there is a memory map in there near the end of the file. This will tell you
how much you used, how much is left, and where it is located in case you
use ORG statements and left some holes.
