) within this thread instead
of passing it to the operating system. The thread must be large enough to contain all
fixed size buffers. If the thread is full, variable sized buffers may be allocated outside
the thread, provided that profile parameter OVSIZE
allows this.
THSIZE
is ignored if it is specified in
a parameter string activated by a SYS
or PROFILE
profile parameter or in an alternative
Natural parameter
module (as specified with the PARM
profile parameter).
THSIZE
can reduce the number of switches
into TCB mode, because of the reduced number of physical GETMAIN
s. The same
applies if profile parameter WPSIZE
is used.
