the following publications: • For information about the that
you are using, including procedures for
gaining access to the VM/310 system and
logging on, see the GC20-1810. • If you are using an IBM 3761
Communications Terminal, the IBM GA18-2000, is a
prerequisite. • The CP commands that are available to
you as a general user are described in
IBM Virtual Machine GC20-1820. For additional tutorial information on
using CM, you may want to use IQf = ! SR20-4438. If you are going to use an IBM Program
Product compiler under CMS, you should have
available the appropriate program product
documentation. These publications are
listed in GC20-1800. COREQUISITE PUBLICATIONS The Virtual Machine all
of the error messages and system responses
produced by the eM commands and EDIT and DEBUG subcommands referenced in this
publication. It also lists the error
messages issued by the EXEC processor
during execution of your EXEC procedures.
If you aLe alternating between eMS and
other operating systems in virtual running under VM/310, you should consult in GC20-1821.
