Primary Commands
These are stand-alone commands which provide the primary functionality in a script. These
commands may rely on one or more of the Secondary Commands to provide values for some
parameters. The preprocessor will require that these commands appear only as the first element
of a command line. The start of a command line is delimited by any of the following:
The start of a new line of text in the script
A semicolon (';')
A left brace ('{')
