DDABCD
(1) Converts decimal ASCII data stored in the area starting from the device designated by to 8-digit BCD data, and stores
it into the area starting from the device designated by .
For example, if the ASCII code of 87654321
H
is designated for the area starting from , the operation results would be
stored at +1 and in the following manner:
(2) The ASCII data designated at to +3 can be in the range of from 0 to 99999999.
(3) The ASCII code set at each digit can be in the range of from "30
H
" to "39
H
".
(4) If ASCII code for individual digits is from "20
H
" to "00
H
", it is processed as "30
H
".
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
Program Example
(1) The following program converts the decimal ASCII data set from D20 to D22 to BCD 4-digit data, and outputs the results
to Y40 to Y4F.
