You have to take the read in String, and treat him with left/right/mid/ 
split

for words see 'split'   

for chars a for-next/each with mid (String,start,length) to use
   
    for nI = 1 to len(string)
        myChar=mid (String,nI,1)
    next

another way is after open to navigate with 'seek' in the file

don't know,
but classic reads are a LOF (end of line) or EOF (end of file).
And once a line or file in the buffer, you can treat it without phisical 
action on a media.
