When "20H" exists between the sign and the first non-zero number (a signed value is specified)
When "30H" exists between the sign and the first non-zero number
• Store sign data, "space (20H)" or "- (2DH)" in the 1st byte (low-order 8 bits of the head device set in (s)). Only the ASCII
data "0 (30H)" to "9 (39H)", "space (20H)" and "decimal point (2EH)" can be stored from the 2nd byte to the "00H" at the
end of the character string in (s). If "- (2DH)" is stored in the 2nd byte or later, an operation error occurs.
Error code
(SD0/SD8067)
Description
2820 The device specified by (d1) exceeds the corresponding device range.
When "00H" is not set in the corresponding device range after the device specified in (s).
3401 The number of characters of the character string specified by (s) is other than 2 to 13 characters.
The number of characters of the decimal part of the character string specified by (s) is other than 0 to 10 characters.
The relationship between the total number of characters specified by (s) and the number of characters of the decimal part is other than
