A simple CL procedure

A simple CL procedure that reproduces the tutorial example looks like:

procedure cltest (datafile)
string datafile
begin
   begplot xw
   readf (data=datafile, xcol=1, ycol=3, all=yes, mode=h )
   dlimits
   boxframe
   points 3
   label ("X axis", "Y axis", "PLOT TITLE")
   endplot
end

If you enter this text into a file say called cltest.cl and use the following commands from CL.

po> task cltest = cltest.cl
po> cltest pongoexamples$tutorial.dat

The data from the tutorial example will be plotted as before. One immediate advantange of this method is that we can now plot data from columns 1 and 3 of any file.

Another way in which you can create CL scripts is to use the mkscript command.
