Hi Bill,

from a user's point of view I love it. I have several cases where this
would be useful including my current main use for gnuplot on an embedded
system.

In view of the relatively light overhead it seems like a very good feature.

I would imagine that the biggest problem would be defining the syntax
for the commands to integrate this idea rather than the implementation
itself. I'll let the core devs reply on that issue.

Are you willing to send me your perl script? I may well implement the
same idea in awk rather than waiting for an eventual integration of this
feature in gnuplot (the embedded does not have perl)


Best regards, Peter.
