2# Statements
3
4Statements describe what the program does. The original Dartmouth BASIC
5was separated into a compiler and operating system with statements like `GOTO`
6and `PRINT` for the compiled language and commands like `SAVE` and `LIST`
7for controlling the system. 64K BASIC is a unique implementation where
8everything is compiled and executed by a virtual machine. There are no
9commands, everything is a statement.
10
11Statements tend to be short and it's common to put multiple statements on a
12single line. Use a colon `:` to separate statements. This works in both
13direct and indirect modes.
14
15```text
16FOR I = 1 TO 10 : PRINT I : NEXT I
17```
18
19Statement words can never be used in variable names. 64K BASIC will insert
20spaces to help you when you accidentally include a word in a variable name.
21
22```text
23LET BONK = 1
2410 LET B ON K = 1
25```
26
27Statements need to be properly formatted with the information they need.
28Angled brackets `<>` are used to indicate required items.
29Square brackets `[]` are used to indicate optional items.
30Ellipsis `...` indicate items that may repeat.
31Vertical bars `|` separate mutually exclusive options.
32All letters and punctuation not in brackets are required.
