See Section 1 for an overview of GDSX.
Unless you are already familiar with GDSX, it is helpful to do parts of the tutorial.
Sections 4 and 6 of the tutorial contain step-by-step instructions on configuring and
running an example program and using SCF for management of GDSX objects. You
might wish to skip Sections 5 and 7 on DEVICE^HANDLER and LINE^HANDLER
design.
See Section 3 for material on running GDSX, dealing with space usages and limitations,
controlling configuration parameter values, managing objects by means of SCF,
interpreting warning and error messages, and gathering information if GDSX abends.
See the SCF Reference Manual for GDSX for more information on managing GDSX
using SCF.
