Chapter 4 User Commands
MPE XL provides you with a new type of user command called command files.
Along with the familiar user defined commands (UDCs), command files can
be used to modify and manipulate the MPE XL environment.
* Lesson 1 introduces you to command files, the new user command in MPE
XL.
* Lesson 2 makes a comparative study of UDC files and command files and
discusses the benefits of having both available to you. If you are
not familiar with the creation of UDC files and execution of UDCs,
you may choose to skip lesson 2 and continue with Lesson 3.
* Lesson 3 steps you through the process the MPE XL system uses in its
attempt to execute whatever you type at the prompt. Lesson 4
introduces you to the new XEQ command.
* Lesson 5 introduces you to new features of the SETCATALOG command
that allow easy UDC file manipulation. Lesson 6 discusses the new
RECURSION feature that allows one UDC to call upon any other UDC,
making UDC file maintenance more flexible. Those of you who are not
familiar with creating and maintaining UDC files may choose to skip
these two lessons and the following two lessons, 7 and 8.
* Lesson 7 introduces new user command options. Lesson 8 introduces
the new MPE XL OPTION command. These two lessons assume some prior
knowledge of programming and of creating and maintaining UDCs.
