ALTER Command
? Use the question mark to represent a single unknown character in a specific position;
for example, $ZM01.#Z?1 selects all object names subordinate to $ZM01 that begin
with #Z, end with 1, and contain exactly one character between the #Z and the 1.
ALTER Command
Use the ALTER command to change the values of the attributes of an existing object.
The ALTER command changes only the specified attributes of the target object.
This is a sensitive command.
The ALTER command is supported for the following QIO subsystem object:

SEGMENT
Altering a SEGMENT Object
Use the ALTER SEGMENT command to change the memory pool size of a SEGMENT
object.
The ALTER SEGMENT command allows you to change the size of the current pool
space. This command is most useful to immediately shrink the current pool size when
less pool space is required. Although the QIO subsystem automatically shrinks the size
of the pool space when less pool space is being used, this shrinkage normally occurs
in increments and over a period of time. Note that the rate of shrinkage is slower than
the rate at which the pool space is increased. ALTER SEGMENT is a sensitive
command.
The ALTER SEGMENT command has the following syntax:
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file as described earlier in this section under Output Destinations
on page 4-5.
ALTER [ / OUT file-spec / ] SEGMENT segment-name
, poolsize size [ , unit [ B | K | M ] ]
