table read Vs eeprom

What are the advantages/disadvantages of the tables (programmemory) and the
eeprom of a PICMicro.

With this I mean speed, reliabilty code space usage etc.

I want to know when to use what, and make the choices in the futere myself.
Because of this I don't give any details about my current need for storing
data.

Greetings,

Alexander

These parameters are easily obtained from the datasheets. Some (size,
avialability!) will vary from PIC to PIC.

Yes, I know that.
Some Pic's don't have an EEPROM and the size is different just as the size
of program memory.

What I want to know is when to use what, and on what that choice is based.

I can only find that a table is more reliable than the EEPROM, and some code
samples for both.
But when to use what is still a puzzle to me, I think table reads are better
but the (All??? the 18F) PIC's still have EEPROM's onboard.

That's only partially true, the 18F series can write to programspace also
from Pic code.

I had a little help from Wouter, but still no real reference on when to
choose what.
I quess that if you have a lot to write and the time for it write to program
space, else use the eeprom.
Also what you said can be used but only for reading.

ThanX for the reply
