=== Variable Operators ===

Most operators work with one or two expressions (integers, floating point numbers, strings, and Boolean values), but there are a few operators that work specifically with variables, arrays, and array elements.  These operators will directly change the value stored in a variable.

^Operator^Name^Example^Comments^
|=|Assign a Number to a Variable|a = 9| |
| | |z = "Hola."| |
| | |q$ = 9.9| |
|+=|Add to a Variable|a += 7|Same as a = a + 7|
| |Concatenate to a Variable|f += "."|Same as f = f + "." |
|-=|Subtract from a Variable|a -= 9|Same as a = a - 9|
|*=|Multiply a Variable|a *= 2|Same as a = a * 2|
|/=|Divide a Variable|a /= 8|Same as a = a / 8|
|%%++%%|Increment Prefix|%%++a%%|Increment (add one) the the variable and return the value after the increment. (may be applied ONLY to numeric variables or array elements)|
|%%++%%|Increment Suffix|%%a++%%|Return the value of the variable and then increment the variable by one for the next time it is accessed. (may be applied ONLY to numeric variables or array elements)|
|--|Decrement Prefix|--a|Decrement (subtract one) the variable and return the value after the decrement. (may be applied ONLY to numeric variables or array elements)|
|--|Decrement Suffix|a--|Return the value of the variable and then decrement the variable by one for the next time it is accessed. (may be applied ONLY to numeric variables or array elements)|
|[[fill|fill]]|Array Fill|a fill 99|Fills an array (that was previously [[dim|dim]]ensioned) with a single value (may be a string or numeric expression)|
