All of the READ for random access statement variations may be used with ISAM files. Note, however:
| • | Each open ISAM file channel refers to both an index (IDX) and data (IDA) file. READ operations implicitly apply to only the IDA. |
| • | Although you can manually set the record number variable and read from IDA file independent of the index (as you would with a random access file), typically you would use an ISAM File Statements (codes 1, 2, 7, or 8) to establish the record number. |
See ISAM File Statements for examples of ISAM operations involving READ statements.
