PUT ‘AB’
PUT ‘AB’
:
WRITE 1
One character is expressed in a code consisting of 7 bits.
To distinguish roman characters from katakana, SI (shift in) code is put in front of a roman character while SO (shift out) code in front of katakana. If, however, roman characters (or katakana) come in succession, SI (or SO) code is not attached to each of the characters. In the above program, SI code is put at the head of the data, and so the data size exceeded 161 bytes, resulting in this alarm.
Measures to Take
Check the GET/PUT command.
