Primary Syntax Elements

The PxPlus language uses a standard set of keywords and symbols to deliver instructions in a statement, as well as to create/execute programs. Some of these are required to make statements executable, while others are used to further define the tasks and the data in the operation being performed.

The primary elements in the PxPlus language are grouped as follows:

Element	Description
Directives	Commands that tell the system what task is to be performed.
System Functions	Numeric or string operations that process values and yield results within a program statement.
System Variables	Internally-defined numeric and string variables for providing system information, such as the date and time.
Mnemonics	Special control sequences for output to a display device or printer.
System Parameters	Options for controlling a system's operation under PxPlus.
Control Object Properties	Named attributes for modifying graphical user interface control objects.
