Or der of Pre ce dence
The process order of many operators within an expression is called the 'order of precedence'. Priority of the same
kind of operator (From left to right, from top to bottom)
Arithmetic operator: ^ ( * , / ) ( % ) ( + , - )
Bitwise & Shift operators: From left to right within the expression
Comparison operator: From left to right within the expression
Logic operator: Not And Or Xor,
• Arithmetic operator is higher priority than a Bitwise operator
• Bitwise operator is higher priority than a Comparison operator
• Logic operator is higher priority than an Assignment operator
Main Functions and Sub-functions
The macro must have one and only one "Macro_Command main()" function which is the execution start point of
any macro file. Any sub-functions must be pre-defined and written before the main() function.
The format is:
Any other sub functions must be declared before the main() function can use it, for example:
Local and Global Variables
Local variables exist only within the function in which they are defined.
