The receiving data area need not be of the same length as the original communication area; if access is required only to the first part of the data, the new data area can be shorter. However, it must not be longer than the length of the communication area being passed. If it is, your transaction may inadvertently attempt to read data outside the area that has been passed. It may also overwrite data outside the area, which could cause CICS to abend.
