DBL$ subroutines

The majority of the DBL$ subroutines are syntactically and functionally identical to subroutines with the same name but without the “DBL$” prefix, with a few exceptions noted below. Refer to the specified pages for the correct syntax for each. We recommend you use the identical routine instead of the DBL$ one.
