| 1. | Sequential files were less common once line files could support long lines.
|
| 2. | This allows for rapid sequential file reads and writes.
|
| 3. | A typical statement in BASIC to write to a sequential file would be as follows:
|
| 4. | IFASMFDP can also be used to split existing SMF sequential files and copy them to other files.
|
| 5. | Wherever possible, the software operated in FORTRAN processing sequential files to enhance portability among operating systems.
|
| 6. | Insertions can be very slow in a sorted sequential file because room for the inserted record must be made.
|
| 7. | Sequential files are generally only readable sequentially from start to end, or written by appending to the end.
|
| 8. | TYPE = SEQWL "') are similar to Sequential Files, except that their line numbers were explicitly stored.
|
| 9. | Partitioned datasets ( PDS ) were sequential datasets subdivided into " members " that could be processed as sequential files in their own right.
|
| 10. | Even something as simple as writing a " sequential file " is coded differently e . g . in Z / OS than in Z / VSE.
