The following symbols are characters that specify how to combine, compare, or modify the values of an expression. These will be used in performing math operations, setting variables, and comparing operators or variables in conditional statements (ifgoto, ifgosub).
Arithmetic
Symbol |
Name |
Description |
|
|
+ |
addition |
Adds numeric expressions. |
||
-- |
decrement |
Subtracts 1 from the operand. ** Not implemented yet |
||
/ |
division |
Divides expression1 by expression2. |
||
++ |
increment |
Adds 1 to an expression. ** Not implemented yet |
||
MOD |
modulo |
Calculates the remainder of expression1 divided by expression2. |
||
* |
multiplication |
Multiplies two numerical expressions. |
||
- |
subtraction |
Used for negating or subtracting. |
||
Comparison
Symbol |
Name |
Description |
|
|
== |
equality |
Tests two expressions for equality. |
||
> |
greater than |
Compares two expressions and determines whether expression1 is greater than expression2; if it is, the result is true. |
||
>= |
greater than or equal to |
Compares two expressions and determines whether expression1 is greater than or equal to expression2 (true) or expression1 is less than expression2 (false). |
||
!= |
inequality |
Tests for the exact opposite of the equality (==) operator. |
||
< |
less than |
Compares two expressions and determines whether expression1 is less than expression2; if so, the result is true. |
||
<= |
less than or equal to |
Compares two expressions and determines whether expression1 is less than or equal to expression2; if it is, the result is true. |
||
Assignment
Symbol |
Name |
Description |
|
|
= |
assignment |
Assigns the value of expression2 (the operand on the right) to the variable, array element, or property in expression1. |
||
String
Symbol |
Name |
Description |
|
|
+ |
concatenation |
Concatenates (combines) strings. |
||
" |
string delimiter |
When used before and after characters, indicates that the characters have a literal value and are considered a string, not a variable, numerical value, or other element. |

Examples:
Arithmetic
// Math! myVar=2 echo 10 * myVar Result: 17:49:02 20 17:49:03 Script stopped
Comparison
// Testing two numbers using comparison ifgoto (1 != 2) doesnot echo "They are equal!" end label doesnot echo "They are not equal!" end Result: 17:25:54 They are not equal! 17:25:55 Script stopped
Assignment
//Setting a variable called myVar and giving it a value of 1. myVar=1 echo "My variable is " + myVar Result: 17:47:31 My variable is 1 17:47:32 Script stopped
String
//Combine two strings together to form a greeting myVar="Hello" myVar2=" there!" echo myVar + myVar2 Result: 17:56:38 Hello there! 17:56:39 Script stopped
