Hi,
Can we access vsam file using clist. If yes, is it there any sysnax change as compared to access of nonvsam files using clist?
Thanks,
Sampath |

as of this moment, CLIST has no access.
Rexx, as delivered by IBM, has no direct vsam abillities.
there is a module (search the forum) that can be obtained free on the web, REXXVSAM (I think).
This can be CALLed from a rexx script (maybe even CLIST)
I would suggest that you forget CLIST and learn/use REXX. |

You can invoke IDCAMS and perform extremely basic tasks such as retrieve a record by key and then replace it in the KSDS.
Apart from that, nothing else. |

Why would you believe this? You were told about reading/updating via idcams as well as the possibility that rxvsam might do what you need.
Whether you can successfully use these depends on your requirement which you have not described. |

My Requirement is as follows:
I use a vsam KSDS as input which will be opened in i-o mode(read and update). The vsam has to be read useing key field which comes from a screen using clist.
If key is found in vsam display the record on screen where nuser will have option to edite the data, and then same data is updated in vsam file.
i guess this data is sufficient, everything needs to be handled in clist. |

It's over 15 years since I've even looked at a CLIST, and I'm not going to start ploughing through the manuals now 
I might have some REXX code that does the same sort of thing. Will post it if I can find it. |

The REPRO statement is supported in REXX so should be in CLIST too
| Code: |
" REPRO IFILE(KSDSIN) OFILE(WORK) FROMKEY("KEYIN") TOKEY("KEYIN")" |
So by building the command above, using REXX, it is also executed. |
