The $GUID function generates the unique identifier. It has two parameters:

• (optional) Use upper case. If this parameter is 1 or 'true' the engine creates output in upper case. The default is 0 (means 'false').
• (optional) Remove group separators. If this parameter is 1 or 'true' the engine removes '-' from output string. The default is 0 (means 'false').

Examples

1. $GUID() generates GUID using default presentation.
2. $GUID(true,true)) generates GUID using upper case without '-' group separators.
