Notes:

1.TYPE - DI, DIF, DIX, DK, DKF, or DKX. R or RU can be suffixed to the type code only if spanned records are being processed. R signifies that the system is to return the relative track address of the next data record in the area specified by the next address operand. RU signifies that the system is to return the relative track address of either the next capacity record (R0) or

data record, whichever occurs first. If R or RU is used, you must code the length operand as ′ S′.

2.′ S′ - system will supply the operand if you specify ′ S′.
