KEYRESET=variable
controls whether a KEY= search should begin at the top of the index for the data set \
that is being read. When the value of the KEYRESET variable is 1, the index lookup \
begins at the top of the index. When the value of the KEYRESET variable is 0, the \
index lookup is not reset and the lookup continues where the prior lookup ended.

Restriction      Variables with a VARCHAR data type are not supported.
Interaction      The KEYRESET= option is similar to the UNIQUE option, except the \
KEYRESET= option enables you to determine when the KEY= search should begin at the \
top of the index again. See      KEY=index
UNIQUE
