Function
A number (indicated by [S2+1]) of characters starting from the character indicated by [S2] are retrieved
at the left end (beginning) of a string from head address [S1]. The result is stored in elements from head
address [D].
1. If [S2+1] is an odd number, 00H is stored in the higher byte of the element that stores the last character.
2. If [S2+1] is an even number, 0000H is stored in the element after the one that stores the last character.
The source string starts with [S1] and ends with 00H.
When the value in [S2+1] is 0, the instruction is not executed.
If the value in [S2+1] is –1, all data within the range from the character indicated by [S2] to the last
character from head address [S1] is stored in elements from head address [D].

An error is returned in the following conditions. The error ag M8067 is set to ON to identify this error and
the error code is stored in D8067.
1. Error 6705 is returned due to out-of-range search when 00H is not found in elements from head address
[S1].
2. Error 6706 is returned when the value in [S2] is greater than the number of characters from head address
[S1].
3. Error 6705 is returned when elements from head address [D] cannot fully store the read characters
whose number is indicated by [S2+1].
4. Error 6706 is returned when the value of n in [S2] is negative.
5. Error 6706 is returned when the value in [S2+1] is –2 or less.
6. Error 6706 is returned when the value in [S2+1] exceeds the number of characters from head address [S1].
