Basic statements

Below are explained the basic statements of Program and Process and where to declare all the types of variables. For prototyping see Declare.

A list of basic statements:

Basic statements

Program example;
Global // Start a global variables part of the program
End

Const // Start a constants part of the program
End

Local // Start a global variables part of the program
End

Private // Start a private variables part of the main process
End

Begin // Start the main code part of the main process
    proc1(); // create new instance of proc1
    Loop
        frame;
    End
OnExit // Start the exit code part of the main process
End

Global // Start a global variables part of the program
End

Const // Start a constants part of the program
End

Local // Start a global variables part of the program
End

Process proc1()

Public // Start the public variables part of the process
Private // Start the private variables part of the process

Begin // Start the main code part of the process
    Loop
        frame;
    End
OnExit // Start the exit code part of the process

End

Function int func1()
Public // Start the public variables part of the function
Private // Start the private variables part of the function
Begin // Start the main code part of the function
    return 0;
OnExit // Start the exit code part of the function
End

Used in example: basic statements, loop, return, frame

Global, constant, local and private parts of the program can be scattered through the code, between processes and functions. Sometimes the End can be left out, but it's good practice to keep it in. When a variable or constant is declared, it's only viewable or editable for statements beneath the declaration. For more info on that, see prototyping.

Note that when Declare is used, the Public variables have to be declared in the Declare block and not in the process block.
