/* If you want to customize your message then you must change the text in
the above string.
The necessary format of the string for the ALERT routines to properly
display your message is as follows,
xxxx yy <text....> zz cc -- format of alert text string
the meaning of the of the above characters in the format are explained as
follows, (note: each character x,y,z,c represents 4 bits of data, a
hexadecimal digit.)
xxxx - a 16 bit number representing the x position of the start of
the message.
yy - an 8 bit number representing the y position of the message.
<text...> this just means the text of the message
zz - must be set to zero always. i.e. \0
cc - continuation byte, if zero ...... no more text messages
if non zero .. more text to follow.
Note when the format is done as in this program the end (continuation
byte) is missing. This is because C automatically make strings null
terminated. */
