[cc65] Bank Switching on NES

Hi,
i found this old thread on bank switching,but it makes it quite clean on the theory,but i just need an sample on bank switching.
http://www.cc65.org/mailarchive/2002-10/1604.html


i have a lot of const char [] to store in PRGROM.
i guess it should work like this, but how ?

1.use ld65 memory config file to define a memory map (how if i use MMC1),add more bank ROMs in to the config file.
2.use #pragma XXXXX ( what exectly should be written?) 
   to force array value code into certain Segment which defined by the 1st step
3.adding code of bank switching before using data in a certain bank.(combined the thread and the MMC1 reference)

can anyone help? 

thanks
