**Parenthesis** are used to enclose [SUB](SUB) and [FUNCTION](FUNCTION) parameters or to set the operation order in [Mathematical Operations](Mathematical-Operations).
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
> COLOR 14: PRINT [TAB](TAB)(30); "Hello World"
|
||
|
|
|
||
|
|
```text
|
||
|
|
|
||
|
|
Hello World
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
* [SUB](SUB) parameters MUST be enclosed in parenthesis when the [CALL](CALL) statement is used. Do **not** use parenthesis without CALL.
|
||
|
|
* Parenthesis can be used in calculations to determine the order in which math operations are performed when the normal order would not work correctly. Normal operation order is: **1)** exponential, **2)** multiplication or division **3)** addition or subtraction.
|
||
|
|
* Parenthesis can also denote the array index or the dimension size(s) in a [DIM](DIM) statement.
|
||
|
|
* Instead of [BYVAL](BYVAL), use extra parenthesis around sub-procedure call parameters to pass them by value instead of by reference.
|
||
|
|
* Extra pairs of brackets have no effect on the code! If one is missing the IDE should tell you.
|
||
|
|
|
||
|
|
## Example(s)
|
||
|
|
|
||
|
|
Using too many brackets does not harm the code execution as long as they are paired up.
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
nmb$ = STR$(100)
|
||
|
|
nmb$ = LTRIM$(((RTRIM$(nmb$)))) 'extra bracket pairs do not affect the code
|
||
|
|
|
||
|
|
PRINT nmb$
|
||
|
|
|
||
|
|
```
|
||
