i once watched the format of files to which arrays/collections were written. they consist, if i remember correctly, of an identifier followed by the size and then the data. if you write an array to a file you can only read that array back, i think. so it works on datatype base, not on raw memory base if you Read As Datatype. reading as much as possible in one call is definitely faster (that is the reason for which the standard libc streams are buffered by default). reading raw memory arrays of fixed size may be done using memory streams...? do they persist in gambas3? i can't check anything now. regards, tobi ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
