What Is This Training About? Chapter 2 teaches you some of the enhancements that were made to the command interpreter. One such enhancement is a new feature called "implied RUN" that lets you run programs without typing the command RUN. The REDO command has been modified and the new commands LISTREDO and DO add flexibility to the reexecution of commands. Finally, the syntax of the new MPE XL commands has been changed to provide more flexibility. In chapter 3 you will learn about file manipulation. New commands are introduced that will make printing files (on printers and on your screen), copying files, and changing groups much easier. Chapter 4 guides you through the enhancements made to user commands. UDCs have been modified to make them easier to create and maintain. A new type of user command has been added--command files. Chapter 5 introduces you to variables in MPE XL. You can now create and use variables. You can make use of many system variables that are now available. Some of the system variables are user modifiable, such as the variable that defines the prompt character. All variables can be used in user commands, and the system variables can also be used in programs. Chapter 6 teaches you about expression evaluation in MPE XL. The new command CALC allows online calculation of numeric and alpha expressions. In chapter 7 you learn about the command interpreter (CI) program. It is now possible to run the CI from within other programs. This is handy for programmers who want to test programs or for users who wish to test user commands while creating them.
