# Looping

Paragraphs allow simple loops by starting a block of commands
with the loop command and ending that block with the repeat command.
The loop command indicates the beginning of a loop in a paragraph.

## Syntax

```
loop
tcl.commands
repeat
```
Note: The loop statement does nothing
by itself. It must be followed by a repeat statement
to cause the looping effect. Such a loop continues indefinitely unless
terminated by a branch structure. It is not possible to execute the
TCL loop statement from within a paragraph.
