What Does Error Return ?

Subject: What Does Error Return ?
From: Luther Fuller <email@hidden>

I looked in the AppleScript dictionary for information on errors and found this ...

error v : Raise an error

error [anything]

[number small integer] : an error number

[partial result list] : any partial result occurring before the error

[from anything] : the object that caused the error

[to anything] : the desired class for a failed coercion

The AppleScript Language Guide, Appendix C gives some examples, but does not give

an example explaining the the meaning and usage of the 'from' and 'to' parameters.

Does anyone know what these are and where I can see an example of their usage ?
