Maestro Software Manual MAXL Program Language
MAN-MASSW (Ver. Q)
Definitions
A definition is a unique specification of a function or callback. Because definitions
must be unique, a program can contain only one definition for a given program
element.
5.2.2 Program
A program consists of one-translation unit. Execution, in concept, begins in the
translation unit that contains the function run.
MAXL programs consist of following parts:
Global variables declarations
Functions and callback definitions
o global variable declaration for access inside of functions
o local variables declaration
o Program lines.
5.2.3 Startup and Termination
RUN is used to start a program startup. Programs are terminated at the end of a run
function or with the exit keyword.
Program Startup – the run Function
A special function called run is the entry point to all MAXL programs. The compiler
does not predefine this function; rather, it must be supplied in the program text. The
declaration syntax for run is:
Syntax
function run( )
//… Some code
end function
Program Termination
In MAXL, there are several ways to exit a program:
Call the exit operator
Finish program by finishing the run function
Call the return operator from function run
5.2.3.2.1 exit Operator
exit operator immediately ends program flow.
