20000907: GEMPAK DCHRLY QUESTION

Mark,

Your files may be missing the standard FOS characters thatr delineate the
start and end of the product for data commin in off the PIPE or redirection.

The standard FOS product looks like:
^A \r \r \n
#### \r \r \n
SAUS70 etc.


\r \r \n ^C

Without the control characters, a bulletin will not be found.

It sounds like you have started looking down this path already.

Steve Chiswell
