Display Instructions: DISPLAY MESSAGE: MSG(046) Section 3-27
After a message has been registered, the message display can be changed
by overwriting the message in the message storage area.
To clear a message that has been registered, execute MSG(046) with S set to
the message number of the message you want to clear and N set to a con-
stant (0000 to FFFF).
A message registered during program execution will be retained even if pro-
gram execution is stopped, but all messages will be cleared when the pro-
gram is executed again.
Note Refer to Appendix A in the CS/CJ-series Programming Consoles Operation
Manual (W341) for a table showing extended ASCII.
Flags
Precautions Registered messages are updated each time MSG(046) is executed.
All message characters after the null character (00) are converted to spaces
in the Programming Console display.
The character stored in the leftmost byte is displayed before the character in
the rightmost byte.
Examples The following diagram shows how 16 words of hexadecimal data are con-
verted to a message displayed on the Programming Console.
When CIO 000000 turns ON in the following example, the 16 words of data in
D00100 through D00115 are read as the 32 characters of ASCII data for mes-
sage number 7 and displayed at the Peripheral device.
