Which of the following is/are not supported by COBOL?
RBA addressing, Skip-sequential or replacing existing record. |

| RBA addressing and Skip sequential are only supported in CICS. I guess that's what he's getting at. |

The 1st source you cited is for a relative RECORD read. CICS allows a relative BYTE address read. It gives the CICS coder the ability to access an ESDS rec randomly.
The 2nd is not the same as a "skip sequential" read. In CICS the RIDFLD of the read stmt allows the the key to be skipped for the next read without changing modes or the read stmt; just move the new key to the RIDFLD before the next exec of the read. They say that a performance improvement results provided the gaps in the skips are reasonably small. |
