Operation processing
• These functions convert the value input to (s) from STRING data type to BCD (WORD) data type, and output the converted
value from (d).
• The ASCII code 20H (space) that exists in the the string is ignored.
• The ASCII codes 20H (space) and 30H (0) that exist in the string are counted as one character as well.
• Input a STRING data type value to (s) within the following range.
• If the string input has less than four characters, the string will be supplemented with zero(s). (Zero(s) is/are added at the
end of the string.) For this reason, if a string shorter than four characters is to be converted, input a character string padded
with 0s (e.g. '0001' for '1').
• If the string length exceeds 4 characters, the four left characters are regarded as the targets to convert.
• WORD or DWORD data type can be specified for (d). BOOL data type cannot be specified.
