SERVICE Startup Statement
Keywords IBUF(aaa bbb) and OBUF(aaa bbb) have been added to the SERVICE startup statement
to allow default override:
The minimum value for IBUF and OBUF is 512; it is the product of multiplying the buffer size times
the number of buffers. The buffer size cannot be less than 256, and the number of buffers cannot be 0,
so the lower limit would be (2 256) or (1 512).
Enhancements to the Global Exit Facility
The following enhancements have been made to the Global Exit Facility.
IBUF(aaa bbb) If the service name is TELNET, you can use IBUF to specify the number of
input buffers as aaa, and their size as bbb. The lower limits are (2 256);
defaults are (1 1460).
OBUF(aaa bbb) If the service name is TELNET, you can use OBUF to specify the number of
output buffers as aaa, and their size as bbb. The lower limits are (2 256); the
defaults are (4 1460).
