where rw means reading as well as writing. I just want to be able to
replace 100 but not during trading just when I am checking my basket
after I set it up. Then I can compare exit and profit target orders
with the existing positions,

compare it to the real number of shares I have and then adjust the
number 100 if necessary. I know I could open a second file and use
it to write to. I however want to use the same file and change a
number in that file if necessary. In C or C++ or any other language
this is possible. Since AFL uses more or less the C syntax I wondered
if we could do this in AFL as well,

read a file and change some numbers if necessary. Seems that AFL can
only read or write or append. In C or C++ it is possible
simultaneously. Anyone know how to do it in AFL?
