Hello all!

Following Darrel Taylor's excellent instructions, I was careful to WRITECODE to 4 word (complete) blocks starting at $1800 (or any other address where the two LSBs are 0's). I still saw wrong stored values. Every 6th address (and a few others) had an error ... VERY strange behavior.

I had been using 12 WORD sized array variables of 3 elements each, stuffing the last 2 variables of each array into memory (WRITECODE). Suspecting that array variables were the culprits, I changed to 36 individual WORD variables along with all the repetitive code required. NOW IT WORKS!

The PBP manual (pg 25) says clearly that "The compiler will assure that arrays, as well as simple variables, will fit in memory before successfully compiling."

My code is about 4100 WORDs in size. It compiled just fine, albiet showing three notes at the bottom of the screen that code page boundaries were being crossed. I had assumed that since the code compiled just fine, that the 3 warnings pertained to the overall size of my code. BUT, perhaps those were warnings that arrays would not work.

BUT why did it still compile OK? Did the PBP compiler let me down?

Makes me wary of using array variables. I need to learn more about this in the future!

Thanks again to all for your help!
