What does it mean when EIBCALEN is equal to zeros?

Answer Posted / thomas vt

EIBCALEN equals to zero means that the communication area
length is zero indicating that currently no data
transaction has been occured and it is the initial state of
runing that program..

and also the communication area length will increased
according to the length of data transmitted...
i.e we can pass data from one program to another by sending
it as a group item under the DFHCOMMAREA variable used in
program
