thank you very much PCM programmer. i looked at the link that you gave me but is there another way of assigning values to the array without declaring another array as constant? My purpose is to save RAM. I have so much data to send out from the PIC. I want to do it using arrays instead of having a long series of PUTC's in my program. Thank you so much for your immediate response. It is highly appreciated.

At the end of the day, the values have to be stored somewhere...
You can declare an array at initialisation, with the standard:

int array[10] = {1,2,3,4,5,6,7,8,9,10};

Using hex values, but the compiler will still effectively generate a constant array, and just automatically copy it to RAM for use at the start of the code.
Declaring a number of constant arrays, and copying just the one you want to RAM when needed, allows a single RAM area to be used, rather than multiple areas, but obviously the constant arrays have to exist to hold the values. They only use ROM though, not RAM.

Best Wishes
