Variables
Variables that hold numeric values must begin with a letter, and may consist of any number of alpha-numeric characters. They are case sensitive. They may be used interchangeably with numeric constants.
Variables that hold string values follow the same rules as numeric variables, but must end with a dollar sign ($). They may be used interchangeably with string constants.
When you assign a numeric value to a string variable or add a numeric value to a string (concatenate) the number will be automatically converted to a string before the operation is completed. A string value may not be assigned directly to a numeric variable or array element without manually converting it's type using the Int or Float functions.
| Variable Assignment | |||
|---|---|---|---|
| Operator | Name | Example | Comments |
| = | Assign a Number to a Numeric Variable | a = 9 | |
| = | Assign a String to a String Variable | z$ = “Hola.” | |
| = | Assign a Number to a String Variable | q$ = 9.9 | |
| += | Add to Numeric Variable | a += 7 | Same as a = a + 7 1 |
| += | Concatenate to String Variable | f$ += “.” | Same as f$ = f$ + “.” 1 |
| -= | Subtract from Numeric Variable | a -= 9 | Same as a = a - 9 1 |
| *= | Multiply Numeric Variable | a *= 2 | Same as a = a * 2 1 |
| /= | Divide Numeric Variable | a /= 8 | Same as a = a / 8 1 |
