[5,5]		Standard I/O library for C programs
-----		-------- --- ------- --- - --------

This library contains all modules that compile differently for
RSX and RT11 support, along with some modules, such as printf.mac,
that are heavily tied to the I/O library conventions.

The library is built using one of the following command files:

RSTS/RSX	RSTS/RT11	VMS		RSX-11M		RT-11
--------	---------	---		-------		---------

XMAKLB.CMD	RMAKLB.CMD	VMAKLB.COM	MMAKLB.CMD	TMAKLB.COM

Please read and understand the command files before executing them.  In
particular, note the special handling of ATOD and DTOA.  Small "stubs"
are placed into the library (the real ones are rather large).  If you
need floating conversions in printf() and friends, explicitly link in
DTOA.OBJ to override the library stub. Likewise, if you need floating
conversions in scnaf() and friends, explicitly link in ATOD.OBJ. This
will cause an increase in your program size.


			NOTE

The RT11.MAC and RSX.MAC command files, as distributed, assume the
existance of the SXT instruction.  This instruction is not present
on the PDP-11/20, the PDP-11/05, and the PDP-11/40 (without optional
EIS).  If C programs or libraries are to run on any of these models,
the command files must be edited to define C$$SXT = 0 before building
the compiler or library.
