According to Andreas Bauer:

can you please explain me how to use the stdin/stdout with gpc? The compiler does not seem to know these.

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 *does* work when stdin/stdout are connected to the terminal, but when using pipes it seems not to work.

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,

Peter
