CMS Command Search Order When yoa enter a command name at the terminal, CMS begins searching for
the command of that name. Once a match is found, the search stops. The
search order is:

Figure 2 shows a basic description of the command search order; you
can find complete details in the YHlllQ CMS Command Summary Figures 3 and 4 contain alphabetical lists of the CMS commands and the
functions performed by each. Figure 3 lists those commands that are
available for general use; Figure 4 lists the commands used by system
programmers and system support personnel who are responsible for
qenerating, maintaining, and updating VM/310. Unless otherwise noted, CMS commands are described in this manual. In these figures, the "Code"
column indicates, for those commands not described in this manual, the
reference source for that command: Section 1. Introduction and General Concepts 7
