Example:
When M0 is ON, the data in D0~D3 is "1234567". When the instruction $DEL is executed, the
characters in D0~D3 starting from the character indicated by the value in D11 are deleted. The
number of characters which are deleted is indicated by the value in D10, and the result is stored in
D20~D22.
If the values in D10 and D11 are 3 and 4 respectively, the execution result is as follows.

If the values in D10 and D11 are 5 and 4 respectively, the execution result is as follows. Owing to the
fact that the number of characters which are deleted exceeds the range, the characters in D0~D3
starting from the fourth character to the last character are deleted.
