ICP300I UNIT ADDRESS EXCEEDS HEX ADDRESS FF

Explanation
The keyword value for the unit address (specified in either the
UNITADD or the ADDRESS keyword in the IODEVICE statement) plus the
keyword value for count (specified in the ADDRESS keyword), minus
one, exceeds the maximum allowable value of (hexadecimal) FF for
a unit address. 

System action
IOCP continues to validate and check the syntax of the remaining
statements. However, it does not generate an IOCDS and it does not
produce configuration reports. 

Programmer response
Correct the keyword values.
