In order to run a sort
the user supplies a file of sorting instructions
written in the sort language.
This data file should contain a description of the experimental
setup, the number of spectra (histograms) required and
a set of commands to be applied to each event being sorted.
The sort package checks the syntax of these
instructions and translates them into a more low level language, i.e. C.
This translation is then compiled to produce a sort program
based on the user's original sort instructions.
If there are mistakes in your sortfile
the sort package reports them as warnings or errors
when you try to set up a sort.
Warning and error messages are given
with the line number
and a copy of the erroneous line.
