Thanks Steve,

there are some interesting "you really don't want to use Open2"
documents around, although I fit the minority when;

a) I know output shouldn't be buffered or anything nasty.
b) I have a trivial command to establish if the program is responsive
(finished writing output).

... so I may "get away" with Open2.

If I can master perl syntax <sic> I should have a working prototype by
tomorrow..

 Simon
