Applications from KAPPA and other packages can be
combined in procedures and scripts to customise and automate data
processing. In addition to giving literal values to application
parameters, you can include ICL or C-shell variables on the
command line, whose values are substituted at run time. It is also
possible to write parameter data into variables, and hence pass them
to another application, or use the variables to control subsequent
processing.
