working with data in flash

This is a rookie question, but I am struggling to find resources on how to do this.

I would like to store some data values in flash (mainly an address) which can be changed at run time (typically only once).

I am using the LM3S101 and IAR EWARM.

1) How do I direct the compiler to place the data at a particular place? e.g. last 1kB of flash

2) What type of qualifier should be used on the variable? e.g. const or volatile

3) Are there any examples or resources that I could look at for more info?

Thanks,
Duncan
