Hsqldb Sotred Procedure

I am trying to setup a stored procedure in my in memory Hsqldb database for testing purposes. The stored proc I am working from is developed in MySql so I want to set it up with HSqlDb to fit in with my testing suite

I am trying to create a simplified version of the procedure but having no joy as of yet

The procedure is

     CREATE PROCEDURE p_recordTaskExecution(IN userTaskId INT, IN isSuccess BOOLEAN, IN statusMessage VARCHAR(2000), IN operationsPerformed INT, INOUT procedureStatus BOOLEAN) 
  BEGIN ATOMIC
  IF userTaskId = 1 Then
        set procedureStatus = true;

  ELSE
    set procedureStatus = false;

  END IF;

  END;

The error I am getting when running my tests is as follows

Caused by: org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement at line 3 of resource class path resource [databaseTesting/inMemory/createInMemoryDatabase.sql]: CREATE PROCEDURE p_recordTaskExecution(IN userTaskId INT, IN isSuccess BOOLEAN, IN statusMessage VARCHAR(2000), IN operationsPerformed INT, INOUT procedureStatus BOOLEAN) BEGIN ATOMIC if userTaskId = 1 Then set procedureStatus = true; nested exception is java.sql.SQLSyntaxErrorException: unexpected end of statement:  required: ;

I have tried a few things but with no joy

Any help on this would be appreciated
