System
APIs
can
appear
daunting
at
first,
but
when
you
dig
a
bit
deeper
you
realize
that
there
are
really
just
a
few
API
concepts
that
once
learned
allow
you
to
easily
access
hundreds
of
APIs.
This
session
will
go
through
the
pros
and
cons,
dos
and
dont's
of
Retrieve,
List,
Open
List,
and
Unix-type
APIs.
Examples
used
in
the
session
will
be
based
on
RPG
with
the
session
handout
providing
the
same
examples
in
CL,
COBOL,
and
C.
By
the
end
of
this
session,
attendees
will
be
able
to
use
the
vast
majority
of
i5/
OS
APIs.
