Arithmetic Modifiers (+= -= *= /= %=)
These operators all act as per their usual function (if the = was ignored), but have the
effect that they substitute the resultant value back into the variable upon which they
were operating. For example:
var %Int = 9
Int += 1
wrt "Int = ", Int, "_n_r"
exit
would print the line:
Int = 10
String Operators
There are a limited number of operators that will successfully manipulate strings.
These are as follows:
+ += = == != < <= > >=
Copying Strings (= + +=)
These operators will copy one string either onto the end of another, or copy one
string to another.
For example:
var $String = "Hello"
var $Result
Result = String + " Everybody"
would set Result to contain the string "Hello Everybody"
Or alternatively:
var $String = "Hello"
String += " Everybody"
would change String to contain the string "Hello Everybody"
String Comparison (== != < <= > >=)
These operators enable strings to be compared.
The == operator will check that two strings are the same, whereas the != operator will
check that they are not the same.
