To change the flash memory from code, you use the spm instruction. You
use lpm to read bytes from the flash memory. Spm and lpm use word
addresses not byte addresses which can cause a bit of fun for the
unwary.

You would not normally store data in program (flash) memory. You would
normally use the eeprom for this.

It is all on page 244 of the Mega32 datasheet.
