I think the scheme Steve Greenfield describes for parsing 3270 input
is going to have problems with fields containing nulls. A keyboard
operator can fill all or part of a field with nulls using the Erase
EOF key or the Delete key. If I remember correctly, only the non-null
characters in a field are sent to the host in response to a Read
Buffer command. If a field contains nulls the string sent to the host
will have fewer characters than the field length. I think Steve
Greenfields algorithm will treat the next SBA character, its address,
and some of the data from the next field as part of the field in this
case.
