| Global Constant | Label | Supported Data Types |
| --- | --- | --- |

| `{!$GlobalConstant.False}` | False | `Boolean` |
| `{!$GlobalConstant.EmptyString}` | Blank Value (Emtpy String) | `Text` |

![Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-platform-platform_automation-264-0-0-production-enus/60568438-ec7e-4665-acd1-7c80dcbe60d5/images/icon_example.png)

Example

When you create a Boolean variable, `$GlobalConstant.True` and `$GlobalConstant.False` are supported. When you create a Currency variable, no global constants are supported.

## Null Versus Empty String

At run time, `{!$GlobalConstant.EmptyString}` and `null` are treated as separate, distinct values. For example:

- When you leave a text field or resource value blank, the value is `null` at run time. If you want the value to be treated as an empty string, set it to `{!$GlobalConstant.EmptyString}`.
- For an orchestration condition, use the `is null` operator to check whether a value is `null`. If the condition compares two text variables, make sure that their default values are correctly set to `{!$GlobalConstant.EmptyString}` or left blank (`null`).
