If you're using the "ROADSEG" shapefile from the Alberta shapefile set,
the output of testawk is:

NID:DATASETNAM:SPECVERS:ACCURACY:ACQTECH:ACQPROVIDR:ACQREVDATE:NATRDCLASS:RTNUMBER1:RTNUMBER2:RTNUMBER3:RTNUMBER4:RTNUMBER5:RTENAME1FR:RTENAME2FR:RTENAME3FR:RTENAME4FR:RTENAME1EN:RTENAME2EN:RTENAME3EN:RTENAME4EN:EXITNBR:NBRLANES:PAVSTATUS:PAVSURF:UNPAVSURF:STRUCTID:STRUCTTYPE:STRUNAMEFR:STRUNAMEEN:ROADSEGID

So if you cut/paste this into your dbfinfo variable it should match.

FWIW, I used the attached dbfawk file on the Alberta shapefile testawk seemed
to show it was working for labeling freeways and setting their lanes/color.
It should give you a starting point for further work.

HTH,
T.
