Script understanding

[petersieg]

Hello.
I tried to enter bcpl source in bravo. Started bravo, press i (for insert).
in Console: start playback test.scr. Nothing appears in bravo?
test.scr:

0 Typeline // Hello world demo
0 Typeline get "streams.d"
0 Typeline external
0 Typeline [
0 Typeline Ws
0 Typeline ]
0 Typeline 
0 Typeline let Main() be
0 Typeline [
0 Typeline Ws("Hello World!*N")
0 Typeline ]

Also on > prompt. Only first line is seen. Not any other line. Same if timestamp is increased.

How can I enter bcpl source in bravo with this?

Thx, Peter
