2.1  DCL Commands for Program Development

  This section describes the DCL commands that are used
  to create, compile, link, and run a PL/I program on an
  OpenVMS system.     Figure 2-1   shows the steps in creating a
  program.

  The commands to perform the actions shown in       Figure 2-1
  are as follows:

   1  EDIT/EDT AVERAGE.PLI

   2  PLI AVERAGE

   3  LINK AVERAGE

   4  RUN AVERAGE

  PLI is the default file type for PL/I source files.  You do not
  have to specify the file type when you compile the source file.

  If your source program compiles successfully, the compiler
  creates an object file with the file type OBJ. If the compiler
  detects errors, the system displays each error on your screen
  and then displays the DCL prompt.

  The /LIST qualifier causes the compiler to produce a listing
  file, as follows:

  $ PLI/LIST  AVERAGE

  In this example, AVERAGE is the name of the program.

  Section 2.3.2 lists the command qualifiers for the PLI com-
  mand.

  To create an executable image file from the sucessfully com-
  piled program, invoke the OpenVMS Linker.  The linker uses
  the object file as input to produce an executable image file as
  output.

  Section 2.4.2lists and explains the command qualifiers for the

  LINK command.

  To run your program after the executable image file has been
  created, use the DCL command RUN.
