Parameters
- INDEV
- Specifies the name of a field containing the input device number, or a register containing the address of a field containing the device number.
- OUTDEV
- Specifies a four byte field in which the converted device number is placed. Can be specified as a label or as a register containing the address of the output area.
- DEVLEN
- Specifies the length of the input device number. Can be specified
as the label of a halfword field containing the length, or as a register
containing the length.
If INDEV indicates a field that is only four characters long, DEVLEN must be specified.
If DEVLEN is not specified, then INDEV must be a field or a register that points to a field that contains the device number followed by at least one blank. The field can be up to eight bytes long. The IATXDEV macro determines the length of the device number if DEVLEN is omitted.
