Well, I don't know whether this is feasible. What would really make my day
would be an option that allows me to send data directly to STDIN of a
running script and have the AppleScript component wait for an application
response with the data written to STDOUT from Perl. Vice versa Perl should
just wait till it receives a data event.

What would I use it for?

I have > 10 MB of data that I can only get at in chunks < 32k (blessed be
HyperCard's storage limits!). The data is linked to an index I need to
consult after every chunk. At the moment I use one Do Script event per 32k
chunk. With a Send Data event as described above I could avoid restarting
one and the same perl script each time I process a chunk (or gobbling up
processing power polling for the output).

Well, give them something great and instead of saying thank you they will
be clamouring for more.

                                            thank you,
