Repeating complex sequences of PONGO commands by hand can become boring and is likely to lead to many mistakes (particularly on those occasions when you want to create a hardcopy and cannot even see the current state). The way to get around these problems is to use the abilities of the ICL or CL command languages to create procedures.
The following two sections show extremely simple examples of how to
start doing this in both languages. To get further you'll need to
consult the appropriate documentation, SG/5 in the case
of ICL and the ``CL Programmer's Manual'' and
``An Introductory User's Guide to IRAF Scripts'' for CL.
