ok, so when you say "listing of a program", you just meant the C source code.
Can you show us some of the errors you are getting?
I suspect you were using v2.1 in the old "C90" mode, and some of the non-standard features of that mode are not supported in C90 mode in v3.xx.
I would recommend reading either "Readme_XC8_for_PIC.pdf" or "Readme_XC8_for_PIC.htm" in your XC8 "docs" folder, particularly the section "4 Migration Issues" for "Version 3.00"
