If I could offer the one piece of advice that will save you the most trouble...
There is NO WAY to know when a 3270 screen is finished loading. There are a lot of ways that SAY they tell you when it's done, but they are all wishful thinking.
With so many variations in the way the data stream gets from the mainframe to your emulator, there are just too many ways to trip up any detection method. Every five years or so, someone produces a new product that works around EHLLAPI, and they all end up with the exact same problem: premature emulation.
So, always plan to do some real tricks to make certain you are where you think you are when write your scripts. You have to watch that "busy" light for sure, but it may be flashing so quickly you can't see it (but the EHLLAPI can). So you have to back that up with checking for strings to be presented in the presentation space. (but if compression is turned on, that may not happen). |

| I used to use a product called OSPI (Open Systems Protocol Interface) from BMC to access 3270 screens from the BMC Mainview Automation environment. CA has a similar tool that I believe is more batch-oriented, although I don't recall the name off-hand. |

Suggest you start with - what is necessary, then what is possible - hopefully, soon you'll get what you need.

Anuj,
That would be a great start to a different thread!!! I'd rather sit in pub/bar/huka and talk about it face-to-face, but alas, we're too far flung. |

Mackinney Systems sells a product named "SPY" -
www.mackinney.com/products/mainframe-security/spy.html
Look at the bottom of the above link for a product named "Show and Tell".
Over 25+ years ago, I wrote a prehistoric preemptive CICS screen-stealing facility, with the main transid named "ICU2" (I SEE YOU TOO), but there are better products available in the market today.
It was fun....  |
