20010314: plotting data values with MARK in sfmap

Dave,

MARKER is not a parameter in SFMAP in 5.6+.
Instead, you can specify MARK in the sfparm value.
(this allows you to specify marker based on value
as well as color coding the markers using the COLOR=() syntax).

I see your script plotting SGNL uses MARKER. THat may be the simple problem.
