Description of Syntax

The individual commands are treated in alphabetical order in the following section. The novice would be well-served by reading the treatments of the data, model, newpar, and fit commands, in that order, then the other commands as needed. The write-up for each command includes a brief description of the purpose, an outline of the correct syntax, a more detailed discussion of the command assumptions and purpose, and a series of examples. Some commands have one or more subcommands that will be similarly described following the command.

In the command description, the syntax uses the following conventions:

• <an argument> - an argument to the command
• <compound argument> =:: <argument a> <argument b> - the definition of a compound argument
• <an argument>... - a repeated string of arguments of the same type
• [<an argument>] - an optional argument
• <arg a> or <arg b> - a choice between an argument of type < arg a > or < arg b > must be made.
