    HI,

    I need to translste a file from one chr to another chr, What is the best way - good performance - to achive that task?
    0) read the file

    2) used Instr command ?
    3) any other way???

    Open the file in binary, input all chr's in a byte array, use your algoritm (since you didn't tell us i guess you know) to convert each chr to the correct one

    Code:
    dim buffer() as byte
ff=freefile
Open yourfile for binary as ff
get ff,,buffer
close ff
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
