• It is assumed this task will only plot HK or AUX and GTI data for the PPS processing. It has been made general enough to plot any non- string parameters from any file.
• The task defaults to plotting a TIME column if no value for parameter ``xcolumnname'' is entered.
• The task defaults to writing a postscript plot, but in principle can accept any pgplot compatible device, which also lends this task to producing interactive plots at some later stage.
• This task supports vertical (portrait) as well as the default landscape plots. This is accomplished by entering the value ``/VPS'' as the plot device instead of ``/PS''.
