I am totally confused on IMS message segments. When I
create a message and it contains 5 segments does the entire
message have a 32k limit or does each segment have a 32k
limit? Is there a setting in the stage1 sys gen that
defines if a transaction can receive/send multi-segmented
messages?

Answer / leopold holubar
Every message segment can contain up to 32k message length. As far as I know there is no limit to the number of segments, so the total message length, if you add the segments together, is virtually endless. The transaction definition determines if the input to a transaction is single or multi-segment. In contrast to that, every transaction can write single or multisegment output - there is no change in definition required for that. In the "old style" generation process in stage1 the (input message definition) parm is MODE=SINGLE or MODE=MULTI.
