    The files in this archive are RPL words for accessing system library
calls(AMIGA ONLY). These new words will allow you to directly call library
functions.  In Real3D 2.47 the manual has three words for this (LIB_CALL,
LIB_CLOSE, LIB_OPEN) which where never implimented(why?).  The included file
(system.rpl) when loaded into RPL will define these words.

    The defintition of LIB_CALL is slightly different then in the manual.
I have define individual words to access the data and address registers
(ie. D0@ D0! D1@ D1! ...), also the D7 and A7 registers are not defined.
D7 is used as the offset for the function call and A7 is left as is, so
as not to disturb the system stack. This will not cause any problems with
any library calls that I know about.

            files included in this archive are:

    system.rpl      (Defines main words)
    DOS.rpl         (Defines commonly used DOS Library functions)
    iff_parse.rpl   (Defines commonly used IFFprase library functions)
    readme          (This file)

    To install just copy files to the "REAL:rpl/sys" directory and use
the LOAD word in a RPL window or edit the rpl-startup file in the "REAL:s"
directory if you want the words defined in the master enviroment.

NOTE:
    The extra word SP>DP is used to change a single precision floating
point number stored as an interger on the parameter stack to a normal
floating point number on the stack.
    These files should work with versions higher than 2.5 but I can't
say for sure because I haven't upgraded to 3.0 or higher. These files
will not work on the PC version of Real3D and will most likely crash the
system.

    If you have any suggestions, bugs, or problems contact me.
