Hi all
I had two queries
1. PROGA --LINK---PROGB---XCTL---PROGC
if i issue a GOBACK from PROGC where will the control go & what if i do cics RETURN.
And in same way what if i do from PROGB ( goback & return)
2. PROGA (retrieve data from DB2)---LINK---PROGB(manipulates data)---LINK----PROGC(send some map) how the psuedo conversation technique can be explained in this scenario? |

For your question 1, click on the Manuals link at the top of the page, find the CICS Application Programming Guide, and read section 1.3.4.1 Flow of control between programs and subprograms. Your questions are answered, very precisely, there.
For your question 2, remember pseudo conversational means after a map is sent, control returns to CICS. So your PROGA, PROGB, and PROGC would have to be written to take into account whether or not a map was sent and if so which program will do the RECEIVE MAP. So the answer depends mostly upon whoever coded the programs ensuring the appropriate handling of maps is done. |

Hi Robert
Thanks i got the answer to first question.
And about the second Q ,
is there anything that psuedo conversation technique can be used other than the user inetrference coming ( ie sending maps & recieving maps)
making it clear is the psuedo conversation technique can be used in retrieving data from database or something like that? |

Hello,
If i understand this latest question (and i probably do not), pseudoconversational has nothing to do with where the data might be stored. . . . |

From the CICS Application Programming Guide manual:
| Quote: |
In a conversational transaction, the length of time spent in processing each of a user's responses is extremely short when compared to the amount of time waiting for the input. A conversational transaction is one that involves more than one input from the terminal, so that the transaction and the user enter into a conversation. A nonconversational transaction has only one input (the one that causes the transaction to be invoked). It processes that input, responds to the terminal and terminates.
Processor speeds, even allowing for accessing data sets, are considerably faster than terminal transmission times, which are considerably faster than user response times. This is especially true if users have to think about the entry or have to enter many characters of input. Consequently, conversational transactions tie up storage and other resources for much longer than nonconversational transactions. Accessing datga in a data base or VSAM file is not a conversation and hence cannot be conversational or pseudoconversational.
A pseudoconversational transaction sequence contains a series of nonconversational transactions that look to the user like a single conversational transaction involving several screens of input. Each transaction in the sequence handles one input, sends back the response, and terminates. |
So by the very definition of pseudoconversational, your question makes no sense. If there's not a terminal involved, you cannot talk about conversational versus pseudoconversational. |

I see you changed your signature line without answering my question.
Not very proud after all, eh comrade? |

Thank Robert/dick
Its clear now..i will get back if i get anything what really the guy meant by asking this question to me...
Phil.. I don't think this is a place to explain or argue on my political views. I have my reasons to believe or not believe and i have the right to do the same.Changing signature/profile picture is nothing to do with your question. I think you got me.. |

Most of us would agree.
Then it would be best that they not be seen - neither in wording nor Avatar.
The forum just cannot deal wth the wide variety of such thoughts people have. . .

| I also agree, but was only responding to akodakka's initiation of the topic by his first and CAPITALIZED signature. |
