I was hoping not to format it but I agree with you about what that would cause. So I will format it in the VCL routine, need then a function to 'find it' when reading a file. Thought I would use the id 'DZ' (5a44) for the first level (needs single fixed for other apps to avoid) then let the user use what they want to identify 'their' data.
