Instruction 72- ASCII Conversion
Expression:
Space Requirement: 1 line x 5 column Location Requirement: Middle, Right rail
Function:
When the input is ON, this instruction converts the alphanumeric characters into the ASCII
codes, and stores them in the register table starting with B. (16 characters maximum).
Execution Condition:
Input Operation Output
OFF No execution OFF
ON Execution ON

Example:
When B030 is ON, the characters ‘ABCDEFGHIJKLMN’ is converted into the ASCII codes, and the
result is stored in 8 registers starting with lower 8 bits (byte) of D0200 (D0200 to D0207).
The Previous Data remains
Note:
Only the number of bytes converted are stored. The rest are not changed. In the above example,
14 characters are converted into 14 bytes of ASCII code, and these ASCII codes are stored in 7
registers (D0200 to D0206). The data of D0207 remains unchanged.
