Hi Richard,

Charles also responded to my email and provided the same information, thanks to both of you although I'm still wondering why I couldn't find that info myself.

I downloaded and installed MPLABX, checked the appropriate box in the program options and recompiled the code for the 16F1847 (MPASM v5.77 now indicated). I am now greeted with error messages (not there when MPASMX unchecked):
"Message[303] C:\PBP\BILL'S RETIC.ASM 1191 : Program word too large. Truncated to core size. (5761)"
followed by another 77 lines of the same but with end number changes.

Does this mean the chip program space is not big enough? It compiles to 7789 words used while the 18F2620 compiles to 14146 bytes.

While I'm here... how does one capture/copy the results messages? I appear to highlight it (turns black) but ^c has no effect.

Thanks for your patience and sharing of knowledge.

Kind regards,
Bill
