Welcome! FYI, there are a bunch of us out here just itching to have  
somebody ask some questions to which we might know some answers. We  
may be behind the curve on the cutting-edge stuff, but we know the  
BASIC part of FB inside out!

I'm not clear what you are trying to do with your arrays, but the  
most common (and fastest) way of writing arrays to disk is probably  
WRITE FILE. It works out something like this (pseudo-code):
WRITE FILE DeviceID, startAddr, numBytes

DeviceID is the ID used when you opened the disk file (I usually just  
use 1)
startAddr is the beginning of your array, which you can get with    
numBytes is the length of the array in memory. Calc it with SIZEOF 
(theArray(0)) * numberOfCellsInArray

Remember that the number of cells will be 1 more than the number in  
the array DIM statement to accommodate cell 0.

To get the array back from disk, you just reverse the process using
READ FILE DeviceID, startAddr, numBytes

Don't hesitate to ask if/when you need more
