## Description

The `concat` function joins multiple values into a single string, automatically adding spaces between each value. This is useful for building display strings and messages.

## Examples

```expression
FullName = CONCAT(FirstName, MiddleName, LastName)

```

### With Numbers

```expression
Message = CONCAT("Total:", 42, "items")
// Result: "Total: 42 items"
```

```expression
Label = CONCAT(ProductName, "-", Size, Color)
// Result: "Widget - Large Blue"
```

## Use Cases

- **Display strings**: Build user-facing text
- **Labels**: Create composite labels
- **Messages**: Construct messages from parts
- **Reports**: Combine data for display
