Search Parameter

The optional "KEY" and "SEARCH" parameters are used with internal files opened for KEYED processing. After the string expression is evaluated (usually a simple string variable or constant), the system reads the first record which matches the key field. If a KEY or SEARCH clause is not specified, the system inputs the next record in key sequence.

For complete information about the KEY and SEARCH parameters and the "=" and ">=" operators (used for full and partial matches either exactly equal or "next greater"), see more in the Index Facility.

Used in these statements:

• Read file
• Restore File
