Description

   LIB$GET_LOGICAL provides a simplified interface to the $TRNLNM
   system service. It provides most of the features found in $TRNLNM
   with some additional benefits. For string arguments, all string
   classes supported by the Run-Time Library are understood. The
   list of item descriptors, which may be difficult to construct in
   high-level languages, is handled internally by LIB$GET_LOGICAL.

   See the description of the $TRNLNM system service in the VSI
   OpenVMS System Services Reference Manual for more information.
