Dear Ruud,
Thanks for your feedback (even though I eventually found a different solution).
> See "writebin"
Unfortunately, writebin is not very helpful here, because you cannot chain writebins :
what I mean is that, if you start one GP session and do x=1;writebin("xInBinary");,
open a second session and do read("xInBinary");y=x+7;writebin("yInBinary");, open a third session and do read("yInBinary");,the GP interpreter will remember the x but not the y.
But this is exactly the functionality I'm looking for here, that of separating several expensive
subcomputations inside a global computation. You cannot do that with writebin.
