Explanation:
1. The signed decimal binary number in S is converted into the ASCII code, and the conversion
result is stored in D.
2. The instruction supports SM690, which controls the ending character.
3. The value in S used in the 16-bit instruction should be within the range between -32768 and
32767, and should be a six-digit binary number. The operand D occupies four word devices.
The data is converted as follows.
b15
S
16-bit bi nar y number
If SM690 is OFF, 16#0000 is stored in D+3. If SM690 is ON, the value in D+3 is unchanged.
Besides, if the value in S is a positive value, the sign character in D is 16#20. If the value in S
is a negative value, the sign character in D is 16#2D. For example, if the value in S is -12345
and SM690 is OFF, the conversion result is as follows.

S
16-bit binar y number
4. The value in S used in the 32-bit instruction should be within the range between -2147483648
and 2147483647, and should be an eleven-digit binary number. The operand D occupies six
word devices. The data is converted as follows.
