The **comma** is used to [TAB](TAB) the cursor after a [PRINT](PRINT) statement's text to tab append another printed value.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
> INPUT "Name, age and sex(M or F): ", nm$, age%, sex$
|
||
|
|
|
||
|
|
* Commas in [PRINT](PRINT) statements [TAB](TAB) space values up to 15 column places with column 57 being the maximum per row.
|
||
|
|
* A comma following the prompt text in an [INPUT](INPUT) statement does not display a question mark. A [Semicolon](Semicolon) or no prompt does.
|
||
|
|
* Commas are also used between [INPUT](INPUT) statement variables when more than one input is required.
|
||
|
|
* [LINE INPUT](LINE-INPUT) can use a comma or [semicolon](semicolon) after the prompt text. Neither will display a [question mark](question-mark).
|
||
|
|
* Commas are used as [argument](argument) separators in many kinds of QBasic statements and [SUB](SUB) or [FUNCTION](FUNCTION) parameter lists.
|
||
|
|
* [WRITE](WRITE) statements use commas to separate values printed to the screen or sent to a file **without tab spacing them**.
|
||
|
|
* **Literal numerical values entered into program code, [DATA](DATA), files or user [INPUT](INPUT) cannot contain comma separators!**

|
||
|
|
|
||
|
|
PRINT , "T"

|
```vb
|
||
|
|
|
||
|
|
value1 = 23567: value2 = 45678: value3 = 354126
|
||
|
|
COLOR 14: LOCATE 2, 1: PRINT value1, value2, value3
|
||
|
|
COLOR 12: LOCATE 4, 1: WRITE value1, value2, value3
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
```text
|
||
|
|
|
||
|
|
23567 45678 354126
|
||
|
|
|
||
|
|
23567,45678,354126

||
|
|
|
||
