Explanation of function and operation
1. 16-bit operation (MIDR and MIDRP)
" +1" characters are extracted leftward from the position specified by of the character string data stored
in and later, and stored to and later.
When characters are extracted from a character string, "00H" is automatically added at the end of the extracted
characters.
- When the number of extracted characters specified by +1 is odd, "00H" is stored in the high-order byte of
a device storing the last character.
- When the number of extracted characters specified by +1 is even, "0000H" is stored in the device after the
last character.
A character string stored in and later indicates data stored in devices from the specified device until “00H” is
first detected in units of byte.
When the number of characters to be extracted specified by +1 is “0”, the extraction processing is not
executed.
When the number of characters to be extracted specified by +1 is “-1”, the entire character string stored in
and later is stored to and later.
Cautions
When handling character codes other than ASCII codes, note the following contents:
The number of characters is handled in byte units (8 bits). Accordingly, in the case of character codes in which 2
bytes express 1 character such as shift JIS code, the length of 1 character is regarded as 2 characters.
When extracting characters from a character string including character codes in which 2 bytes express 1 character
such as shift JIS codes, consider the number of characters to be extracted in units of character codes for 1
character.
Note that the expected character code is not given if only 1 byte is executed out of a 2-byte character code.
