This is not possible directly through dbfawk. The dbfawk language is limited to setting a few specific internal rendering variables based on the contents of the DBF file, and there's no way to *read* xastir internals such as zoom level from a dbfawk file, only *set* them. To accomplish what you want through dbfawk alone would require enhancements to the dbfawk language. > I wanted to display borders in a different line style based on zoom level, > but couldn't figure out a way to do it.

Yeah, hokey, but a usable workaround given dbfawk's limitations. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 AHTB#1 http://kevan.org/brain.cgi?DDTNM "And, isn't sanity really just a one-trick pony anyway?
