IN Subcommand (KEYED DATA LIST command)

IN creates a numeric variable whose value indicates whether or not the specified record is found.

• IN is required. Its only specification is a single numeric variable. The variable can be a permanent variable or a scratch variable.
• The value of the variable is 1 if the record is successfully read or 0 if the record is not found. The IN variable can be used to select all cases that have been updated by KEYED DATA LIST.

Example

FILE HANDLE EMPL/ file specifications.
KEYED DATA LIST FILE=EMPL KEY=#NXTCASE IN=#FOUND
          /YRHIRED 1-2 SEX 3 JOBCLASS 4.

• IN creates the logical scratch variable #FOUND. The values of #FOUND will be 1 if the record indicated by the key value in #NXTCASE is found or 0 if the record does not exist.
