gtpm1m24 | TPF V4R1 Migration Guide: 3.1 to 4.1 |
If you have your own inter I-stream communications code, you must make the
following changes:
- Use system work blocks (SWBs)
rather than IOBs for work blocks and input/output (I/O) (except for
DASD service, which will continue to use IOBs).
- Use the CXFRC macro (rather than the assembler interface) to get
ECBs. You cannot link directly to the GET_ECB routine.
