We have formula code that looks like, for instance
tOldValue := @Environment(“EVar”; “” ) ;
This succeeds in fetching the (non-blank) value of the envt vbl, and also blanking out the envt vbl, in one fell swoop. It is a good thing and it works, but should it work? Or should we recode:
tOldValue := @Environment(“EVar”) ;
@SetEnvironment(“EVar”; “” ) ;
