hi,

I have a query screen. After I input the info and pressed enter, my screen is frozen.

I run /display user usr1 and i got.

Hi - we need to see your code - your logic for getting your message and your logic for sending the screen. Remember that once you communicate - pressing any key - your message will be sent and you will need to handle that logic when you issue your GU for the message coming back. If you give us that info - then we can help.

1. What is IMSAMSG1?
2. How can I get away from a frozen termianl?
3. Is there any way to debug the program?

Thanks.

You are probably hung in response mode because you did not send and receive your message properly. You can get away from a frozen terminal by correcting your code. You will first need to recycle the region - hopefully it is a TEST region. Then you will need to tell us your program code so that we can help you debug it. Remember that once you hit a key, you are communicating with IMS. You are sending a message and hopefully you have coded logic in your program to receive it. You very obviously have erroneous code in your program. IMS is lost and cannot recover.

I've a question for you.. in most of your posts your reply is

Devzee,

Yes! I am very good at IMS. I do not need to see the "moves" - I need to see the IMS code - the retrieval and sending of the message - that would be a start in this situation. If this particular problem were with either the PSB or DBD, DST would not be hung in response mode - he would not have gotten that far. Answer your question?

Devzee & Sandy: These kind of discussions via PM please.

As for the topic: TS should post all info needed. We could have a look at the IMS related coding and if that's ok then advise TS to look for something else like an endless loop. Exploring the MPP via BTS seems a good option to me.

To TS: please post your message processing code (MSG and SPA) as a first step to investigate.

Since I don't own the codes. I have to modfy it before I can post it here.Because I am new to this world, my first thought was it must be something related to the setup or by posting some system message and you would lead me to the right path.

Thanks!

Devzee: not necessary

TS: how can it be you enter /dis command when your screen is frozen? My guess is your program is waiting for input. As stated before we need to have a look at you messagequeue processing.

please explain what is MSG and SPA? how can I get them?
Also, if I have a screen frozen, how can I "re-boot" that termial in order for me to use that termial and user ID again? I am currently using another ID to get the statu info.

Thanks.

/stop and /start. follow the first link in my signature and search for /stop and /start.

Do you kow anything at all about IMS/DC?

An MPP (message processing program) comunicates with users via messages; it receives a message, processes it and sends a message back to the terminal. Intermediate results are stored in the SPA (Scratch Pad Area) which is created for each terminal communicating with one single occurrence of an MPP.

Before working with IMS/DC you should be well trained.
