3.1 Compiling a BASIC Program
  The BASIC compiler performs the following functions:

  .
        Detects errors in your source program
  .
        Generates any appropriate error messages
  .
        Generates machine language instructions from the source
        statements
  .
        Groups these language instructions into an object module
        for the linker

  To invoke the compiler, you use the DCL command BASIC.
  With the BASIC command, you can specify command quali-
  fiers. The next sections discuss the BASIC command in detail
  as well as the command qualifiers available.
