# statement labels

statement labels are used as the destination of a goto
or gosub statement.

A statement label consists of a numeric or alphanumeric
string of characters placed at the beginning of any BASIC statement
or by itself on a line in the program.

BASIC requires labels
only on those statements used as destinations for goto or gosub statements.

Numeric statement
labels can be any of these formats:

- 10

- 1

- 100.5

- 01

- 001

- 10.02

Each of the above labels is unique.

Alphanumeric statement
labels must begin with an alpha character. Any subsequent character
in the label can be alphabetical or numeric. An alphanumeric statement
label must be followed by a : . If a statement
is placed on the same line, it must be separated from the statement
label by one or more spaces.

Because D3 allows null statement
lines, a statement label can stand by itself on a line.

## Syntax

```
statement.label{:} {BASIC statement{s}}
```

## Example(s)

| Label | Description |
| --- | --- |
| 1000 * start main loop | Numeric statement label. |
| mainline: | Alphabetical statement label. |
