Sorry my first message had a error in the code.
Why do I get differing output each time.  Its reading a marked up text file
and the first time it works ok then the next time what looks like memory
dump is added at the beginning of each line then the next time more of the
same and after a while its ok again - should I be flushing memory
somewhere?  Is there a bug in memchar - I've looked but it seems that the
bug that was their is fixed...any ideas? 

help and thanks.
