Hi Walter,

Making the appropriate changes per chip (cmcon, adcon, etc.) and my same code with the same INC file as compiles correctly with the 18F252, I have no luck with a 16F648A or 16F876A.

I thought the INC font string may have been too long also so shortened it to about half its size but no difference. Here is what I get...

With a 16F648A:
Error[113] e:\wjs\pbp260\pbppic14.lib 449 : Symbol not previously defined [EEADRH]
Message[303] e:\wjs\pbp\NOD157~1.ASM 185 : Program word too large. Truncated to core size. (4920)
too many errors

With a 16F876A there are 20 lines of:
Message[303] e:\wjs\pbp\NOD157~1.ASM 187 : Program word too large. Truncated to core size. (4920)

Does this give you any ideas where my problem with 16F's is? What are the chip requirements for using this macro - codespace, ram size, etc,?

Thanks and regards,
Bill
