Your description indicates you understand most of the situation quite
well.  The remaining confusion comes from there being two types of
operations with PCLATH.  A move to PCL loads bits 8 and higher of PC from
PCLATH.  The "pages" that a given value of PCLATH will access are 256
bytes in size.  A CALL or GOTO loads bits 11 and higher from PCLATH.  The
"pages" in this situation are 2K in size.  So if the program is smaller
than 2K, you don't have to worry about "paging" the CALLs or GOTOs at
all, only the move to PCL situations.
