To: Peterdeco1
Thanks for the suggestion, but I do want to write to program RAM (flash RAM) because the EEPROM space will be too small for the 2000 words I want to be able to store eventually.

I appreciate those links and I have read and re-read the good info from Melanie several times. She still does not clarify the need for a ERASECODE prior to WRITECODE, though. In fact, after previous readings of her posts, I had assumed that I needed just WRITECODE and READCODE and that PBP took care of all the details.

Please send more suggestions. I appreciate all help!
Bob
