Function-specific parameter lists

Depending on the setting of the Function_code paramter, a number of function-specific parameters may apply. Table Table 1 summarizes the parameter usage for the function-specific parameters for each of the possible function codes. The function codes are:

X'01' – DataGetFirst
X'02' – DataGetNext
X'03' – DataAbortQuery
X'04' – CheckStatus
X'05' – GetUpdateCode
X'06' – IncSerialNum
X'07' – NewRing
X'08' – DataPut
X'09' – DataRemove
X'0A' – DelRing
X'0B' – DataRefresh

There are no function-specific parameters for Function codes X'07', X'0A', and X'0B', so these function codes are not shown in this table.
