I'd like to write a parser, that can be continued with a new input,

a not finished "nonterminal"
The background:
We have a data structure with some formating information and a 80 char
textfield.
mystruct {int, int, int, char[80]}
In some cases the complete data is stored in more than one
textline. I'd
like to parse the first line and if the text is incomplete the next
line
and so on.
In the moment I copy all possible lines of text in a char[] and start
the parser.
In all my tests the scanner (flex) and the parser seemed to be reseted
to an initial state, wichh leads to "incomplete Syntax".
Any Ideas?
[Replies, cc Help-Bison.] This is normally handled by the lexer. For
more help, you might try the Flex manual,

or perhaps the Usenet newsgroup comp.compilers.
