Number of stacks

For CINET, the range is between 2 and 32. The default is 2. This number determines how many SUBFILESYSTYPE statements must be in the BPXPRMxx member.

If you increase the number of stacks beyond what you currently have specified, each stack is automatically given a numbered NAME. For example, if you add a third stack to two existing stacks, msys creates a new SUBFILESYSTYPE statement for that stack with the setting NAME(TCPIP3). The NAME must match the address space name for the TCP/IP started task as well as the TCPIPJOBNAME parameter in TCPIP.DATA.
