Does EZT interface with ISPF to do this.
If not, then you will need to program a REXX to utilise the ISPF panels and then the ISPF skeletons to build and submit the required JCL / EZT code.
What research have you already done for yourself ??? |

it would be better to spend time on a more common approach...
an ISPF and rexx dialog to build the JCL and submit it for batch processing
running interactively a batch process id frowned upon in any reasonable organization...
the performance approach is to give TSO high priority for short tasks
for long tasks the priority and resources assigned will after a very short time fall below those assigned to batch
so beware! |

Screen processing activities are available only in
CA-Easytrieve/Online and CA-Easytrieve/Workstation.
That means consult those manuals if the product(s) are installed or
ask CA support. |

As far as I know, you can invoke ISPF services from EZT. The only issue is whether you can invoke EZT in foreground...

Ofer,
As Enrico has mentioned the effect of using foreground with long running processes. Also, there is the possibility of tapes being used which in 99.9% of sites can not be accessed via TSO.
But of course I can only really guess at tapes being involved as this is one of those rare posts that misses vital information |

Hello Senthil,
Suggest you consider having the user enter the needed info and then customize&submit a batch job to actually do the comparison.
There are many examples of comparing files using code, Easytrieve, sort, or some other utility. There are also multiple examples of using user-provided to generate jcl and submit this via the internal reader. |
