| ## Overview - Using the DCE Control Program Command Language In DCE Control Program Introduction, we provided a high-level look at some ways to use the DCE control program to administer your DCE environment. In this topic, we will discuss some syntax rules and some of the more important commands you will need to use in composing your dcecp administration commands and task scripts. The dcecp command language consists of DCE administration commands like directory create and object modify, as well as Tcl built-in commands such as if and foreach. We will not discuss DCE administration commands here. These commands are discussed in topics that deal with administering the particular DCE component. Instead, we will focus on using the more generic syntax rules and built-in commands. The Tool Command Language (Tcl) on which dcecp is based is a general-purpose language that is also used for other applications besides dcecp. Although there are many ways you can use Tcl for various purposes, we will limit our discussion to those commands most likely to be used for administering DCE environments. Furthermore, our command discussions do not describe every aspect of individual commands. Rather they suggest why and how you might use a command in the context of administering a DCE environment. If you're not already familiar with Tcl, you will likely need to have access to the appropriate Tcl documentation, including the Tcl reference pages, for writing sophisticated commands and task scripts. ##
