Hello.  I need to write an S-Control to copy the contents of a custom phone number field in a Contact record to the standard Home Phone field in the same Contact record.  (I have a custom Home Phone field in Leads and it won't feed into the standard Home Phone in Contact during the conversion.)

I have general programming experience with VBA, T-SQL, and tiny bit of Ruby, but I don't know where to start with S-Controls.  Can anyone point me to S-Control sample code that does this kind of copy function?

Thanks
David
