stdin/stdout_(re)

According to Andreas Bauer:

The "legal" way is to use ordinary `read', `readln', `write', and
`writeln' operations.  Note that `read' returns a space at the end
of a line, not a chr ( 10 ) or chr ( 13 ), and that `eoln ( Input )'
is `true' instead.

It should work except that the first char is "eaten" by the GPC RTL.
See the thread "[BUG] GPC - a char killer?" on 7. and 11. April in
this list for reasons and a workaround.

Hope this helps,
