SET WORKING SET
SET WORKING_SET is a DCL command that redefines the default working set size for the process, or sets an upper limit to which the working set size can be changed by an image that the process executes. Working set limits cannot be set to exceed those defined in the user authorization file (UAF). Specify the value of n as a number of 512-byte pagelets on Alpha. Note that the OpenVMS system rounds up this value to the nearest CPU-specific page so that the actual amount of physical memory allowed may be larger than the specified amount on Alpha.
