Outline of operation
● This instruction checks whether the specified ASCII code string can be converted using the
ATOB instruction.
● According to the control characters specified by [S1], this instruction checks whether the
ASCII code stored in the area specified by [S2] can be normally converted using the
conversion method specified by [N].
● If the check result is normal, the system relay SRB turns ON (1), and if abnormal, SRB turns
OFF (0).
● Specify the same value as the ATOB instruction for [S1] the control string, [S2] the beginning
of the source data, and [N] the conversion method.
