Compatibility Notes A.24

I/O Control Block

Channel Number Compatibility.

Valid channel numbers are the values 08, 80 to 87, 90 to 97 and the octal values from 00 to 77. Channel numbers with the value 08 and the values 00 through 77 are supported by all V-Series processors.

V300 Channel numbers 80 through 87 and 90 through 97 are not functionally supported. For these channels, an IOC instruction always returns zero for the number of bytes not transferred and an SPIO instruction returns a DLP NOT PRESENT IOP Result Descriptor
V500 All of the above channel numbers are supported.
