eight digits, the UPSI byte is filled in from the left and
zero-padded to the right. If you enter an "x" for any digit,
the corresponding bit in the UPSI byte is left unchanged. resets the UPSI byte to binary zeros. DOSPART nnnnnK
specifies the size of the virtual partition in which you want
a program to execute. The value, nnnnnK, may not exceed the
amount of user free storage available in your virtual machine. You should use this function only when you can control the
performance of a particular program by reducing the amount of
available virtual storage. Section 2. CMS Commands 169

SET In rare circumstances, it may happen that when a program
is executed, the amount of storage available is less than the
current DOSPART. Then, only the amount of storage available is
obtained; no message is issued. OFF --specifies that you no longer want to control your virtual
machine partition size. When the DOSPART setting is OFF, CMS computes the partition size whenever a program is executed.
1. If you issue the SET command specifying an invalid function and the
implied CP function is in effect, you may receive message DMKCFC003E. 2. If an invalid SET command function is specified from an EIEC and
the implied CP function is in effect, then the return code is
-0003.
