Hint Details:

PROBLEM: If a job, run from the XML Jobs menu, fails and results in an error, then this error cannot be cleared and the only way forward is to use the Windows Task Manager to End the Spaceman.exe task.

SOLUTION: The solution to this issue is to handle the error yourself using the <Block></Block>, <Catch></Catch> method.

Simply contain the main body of the script with the <Block> section and in the event of an error, execution will immediately jump to the first line of the <Catch>.

However, please note that it is now up to you to display the error to the user and the option not to do so can be useful if the XML job is to be run unattended.  The <Catch> could even email details of the error to the nominated users.

The error message is contained in the variable 'Exception'.

Example:

<Job autoclose="YES">
 <Block>
   <!-- Inside the 'Block' goes the XML job that was inside the 'Job'-->
   <!-- On an error, execution jumps to the first line inside the 'Catch'-->
   <!-- The actual error message is automatically stored in a variable called 'Exception'-->
   <Parameters>
     <Parameter name="area"/>
     <Parameter name="areaname"/>
   </Parameters>
 </Block>
 <Catch>
   <Rollback/>
   <SetVariable name="extramess">
