C code now doesnt seem right on MPALB X IDE V3.61

[ocset]

Hello,
Please advise why this code is now full of "unable to reslove identifier LATA0"  etc etc , error messages.
This code was fine before.
It was running fine on the micro
I am sure i did not get such errors before.
Its XC8 C  for PIC16F18856

I've copied your code and compiled it without any issues.

I'm using MPLAB X IDE 4.01 with XC8 compiler version 1.45

I did not make any changes, just created a new project with your code as the main.c source file.

Make sure you have the right chip selected, most 16F chips don't support the LAT part of the port, that is the only thing that I can think of that would cause that issue, looks like the xc.h file is included, I usually put it before all of the config defines, not that it should make a difference to finding the LAT definition.
