- 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.

occurs during processing. Can be specified as a label or a register
containing the address of where processing should continue.
