According to the PBP manual, PIC18Xxxxx device variable arrays are only limited by available memory. I have verified there is lots of available memory, but the line:

AIAvgReg var word[128]

gets me this error

ERROR: Unable to fit variable AIAvgReg

Reducing the number of elements to 127 works ok. Even if the limit was one RAM bank, as in older PICS, the 128 Words should still fit in one bank.

Any idea what is wrong?
