-------------------------

This README file contains important information about XA Version 2.0
that may have been left out from the manuals. For the latest information
about XA and its accompanying programs and manuals, read this file in
its entirety. Be sure to read the file XA_200.TXT for complete details
about the operation and features of XA.


Distributing XA:
----------------------
You are encouraged to distribute the SHAREWARE version of XA to your
friends, BBS's, or online services. Please use the pre-zipped SHAREWARE
files that are located in the "X10_ZIP" directory of this distribution
floppy (if applicable).

Please remember, it is a violation of copyright laws to distribute
"REGISTERED" versions of XA without permission from the author.


Warning Messages:
----------------------
XA will display the following message when it encounters a token it
doesn't recognize:

---ERROR--- Invalid expression in statement:
(...statement displayed here...)

You must edit the file where this warning was encountered. XA always
displays the directory and name of the file being parsed.

Note: If this is the SHAREWARE version of XA, see the next section for
tokens that are NOT supported in this release.


Shareware Version:
----------------------
The following tokens are NOT supported in the SHAREWARE version of XA.
- IF, ELSE, ENDIF
- INPORT, OUTPORT
- VIDEO1, VIDEO2, VIDEO3, VIDEO4
- Arithmetic Operators (+, -, *, /)
- Logical Operators (AND, &&, &, OR, ||, |)
- Relational Operators (=, <, >, <=, >=, ==)

You must register XA with the author to have these tokens enabled. Upon
registration, you will receive a registered version and printed User's
Guide. Please fill out the form "REGISTER.TXT".


Using XA with Windows:
----------------------
The following files have been included to help you run XA within Windows.
- xa_event.pif - PIF file for downloading contents of XA.CMD to CP-290
- xa_mon.pif - PIF file for monitoring events and commands.
- xa_power.pif - PIF file for power fail recovery.

Place these files in your Windows subdirectory (normally C:\WINDOWS).
These PIF files expect XA to be in the C:\X10 directory. If this is not
the case, use the Windows PIF editor to modify the settings. See your
Windows User's Guide for complete details. Also, see "Appendix D" in
XA_200.TXT for other important details regarding XA and COM ports.
