Very helpful indeed thanks. So really the .dll can
have access to this record for its own purposes but it
cannot pass this back to MS because it has no string
handling facility?
When a chart is loaded, how does an external formula
"know' the symbol? Does it? Or does this come from the
record structure you talked about?
