Definitions
The sole purpose of a definition is assign a value to a word and therefore make a script easier for a human to read. They do not use utilize any bytecode space in a script as they are not sent to the Cronus Zen. When a script is compiled the words are changed to their assigned value.
define <name> = <value>;
<name> : The name of the constant
<value> : The value assigned to the constant
Only Integer values can be assigned to the value of a constant.
Once a word is defined and given a value, that word can be used anywhere in the script where a value is valid, as shown below;
define my_value = 50;
int myvar;
main {
set_val(XB1_RT, my_value);
myvar = my_value;
if(myvar >= my_value) {
}
if(get_val(XB1_LT) > my_value) {
}
}
A define is a static value and therefore cannot be changed during run time, as shown below;
define my_value = 50;
main {
my_value = 70;
}
If you wish to assign a value to a word and change its value during run-time, you would use a variable instead of a define.
