>IMHO it would be useful to have a look at Postcript stack manipulation operators. >http://www.ugrad.math.ubc.ca/Flat/stack-ref.html Postscript's ROLL operator looks identical to the proposed ROTATE operator from the previous post. ROLL is a better name though. The COUNT, COPY (being a genericisation of DUP) and INDEX look useful as well. (But COUNT would need to be renamed as we already have one of those) Steve Shipway [email protected] _______________________________________________ rrd-developers mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-developers
