The procedure command syntax diagrams are read from left to right, top to bottom. Each command starts with ">>" and ends with "<<". If a command is continued from one line to the next, the first line ends with ">" and the next line begins with ">".
A command can have two types of parameters:
The first keyword parameter used in a command must be preceded by a left parenthesis.
All parameters must be 80 characters or less. All parameters are separated by commas. A right parenthesis is not required, but can be used to end the command.
