This file contains changes for running xloadimage under VMS.  Please
note that this file has not been updated to work with versions of
xloadimage newer than 1.05.  The differences should be fairly trivial.

Jim,

At the bottom of this messages is the diff file for the current release (1.05)
of xloadimage.  In addition to these changes, two new files are also needed for
VMS use only. MAKE_VMS.COM compiles and links xloadimage. rindex.c is my
version of rindex for VMS.  They are both listed below:

-README.VMS---------------------------------------------------------------------
To compile XLOADIMAGE under VMS just use the MAKE_VMS.COM command procedure
provided.

To use XLOADIMAGE you need to define a foreign command.  Here is an example of
how to do it.

   XLOADIMAGE :== $SYS$USERDISKB:[B1F5814.DECWINDOWS.XLOADIMAGE]XLOADIMAGE
