The  AMOS  extensions adds over 70 commands to the AMOS command set to
allow  direct  access  to  the OpalVision framebuffer.  The additional
commands   provide  a  direct  interface  to  the  Opal  library,  for
information  on  the  specific commands see the OpalVision programmers
manual.   The  commands  have  the same names as the Library functions
described in the programmers manual with the prefix 'ov' added (unless
the  function name already starts with 'ov).  For example the function
OpenScreen24 becomes OvOpenScreen24 in AMOS.  See the end of this file
for a complete list of commands.

To install the extension, copy the file 'opal.lib' to your AMOS_System
directory  then  use  the  AMOS configuration program to set extension
number 21 to Opal.lib.


NOTES:

- AMOS screens cannot be opened above line 30.
- This version is for AMOS 1.3 only, the extension will need
to be reassembled for AMOS pro.
