 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
