The TASK macro allocates a task storage area addressable to all socket users communicating across a particular connection. Most commonly this is done by assigning one connection to each MVS™ subtask. If more than one module is using sockets within a connection or task, it is your responsibility to provide the task storage address to each user. Each program using sockets should define task storage using the instruction EZASMI TYPE=TASK with STORAGE=DSECT.
If this macro is not named, the default name EZASMTIE is assumed.
