When the execution condition is OFF, IORS(188) is not executed. When the ex-
ecution condition is ON, both read and write access to PC memory from Periph-
eral Devices is enabled.
There are no flags affected by this instruction.
Example When CIO 000001 is ON in the following example, memory access is enabled.

j MSG(195)
When the execution condition is OFF, MSG(195) is not executed. When ex-
ecuted with an ON execution condition, MSG(195) reads sixteen words of ex-
tended ASCII from M to M+15 and displays the message on the CVSS screen or
other Peripheral Device. The displayed message can be up to 32 characters
long, i.e., each ASCII character code requires eight bits (two digits). Refer to Ap-
pendix H for the extended ASCII codes. Japanese katakana characters are in-
cluded in this code.
If the message data changes while the message is being displayed, the display
will also change.
If not all sixteen words are required for the message, it can be stopped at any
point by inputting “OD.” When OD is encountered in a message, no more words
will be read and the words that normally would be used for the message can be
used for other purposes.
Only the messages whose message number has been preset in the Peripheral
Device will be displayed. If two or more MSG(195) instructions have the same
message number, the earlier message will be replaced when another MSG(195)
instruction with the same message number is executed later.
When a message instruction is executed, its corresponding Message Flag will
be turned ON (bits A09900 to A09907 correspond to messages 0 to 7).
A message instruction can be cleared by executing the instruction with a con-
stant (#0000 to #FFFF) entered for M.
Precautions N must be BCD between 0000 and 0007.
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): N is not between 0 and 7.
Content of *DM word is not BCD when set for BCD.
