Guardian Procedure Calls Reference Manual

Z^LDEV^NUMBER
is the logical device number of the device whose attributes are being returned. The logical
device number could be set to -1. The logical device number of a device can change whenever
a device is configured or the system is loaded. Some I/O subsystems do not have a logical
device number.
Z^DEVICE^RECORD^SIZE
is the record size of the device.
Z^DEVICE^TYPE
is the type of the device. See Appendix A: Device Types and Subtypes for a list of device types.
Z^DEVICE^SUBTYPE
is the subtype of the device. See Appendix A: Device Types and Subtypes for a list of device
subtypes.
Z^LOGICAL^STATUS
is the logical status of the device. These TAL literals are defined in the ZCOMTAL file. Literals
in the zcomc file, for C programs, are the same as those for TAL except that they contain the
underscore (_) character instead of the circumflex (^) character.
