Hi Board,

Is there a place where I can get documents on MAPLESS transaction?

Please can you explain what a MAPLESS transaction is?

MAPLESS transactions are like MPPs which does not have a MAP (Screen ). This are like SUBROUTINES, but they will play independent of the calling program. Something like a seperate thread.

Hope this clarifies...

CICS has maps. IMS has formats. Data in formats is converted to messages by the Message Formatting Service (MFS).

Any transaction can be invoked without a format if the data is keyed in correctly. Iit is just easier not to do it that way in most cases. The coding of a non-MFS invoked transaction is basically the same as one with a format.

I usually refer to the IMS Application Programming Guides but these are not easy to read so you might want to start with the Red Book primer from IBM. A quick search on the internet brought up some other information as well.

Thanks Bithead.

To invoke the background transaction from a BMP or another MPP, insert a message (ISRT) to an alternate PCB (where TYPE=TP) that is either explicitly coded with the transaction in the PSB (NAME=) or is assigned using the CHNG call.

The search trems that I used were +IMS +TRANSACTION. At least one hit should be the IBM Primer.
