Passing data by a COMMAREA

In a pseudoconversational application, CICS ensures that a COMMAREA you specify on a RETURN command is always accessible in read-write mode to the next program in the conversation.

The same is true when passing a COMMAREA within a transaction that comprises more than one program (using a LINK or XCTL command). CICS ensures that the target program has read-write access to the COMMAREA.
