Delete all user defined variables

[DrD]

HVars is a list of HOME user defined variables. DelHVars requires either the element number or the element name from the HVar list, in order to delete a user defined variable. Too bad DelHVars(); doesn't just delete them all, as its namesake implies.

Aside from block loops, is there another way to delete ALL of the user defined variables in the HVars list, via command line or programmatically (without the Vars or Mem keys)?
