Obtaining Group and Field Names in a Map
You can obtain the names of the groups or fields defined in a map at the specified level
using the following syntax of the ASSIGN verb:
ASSIGN OPT=MAPFIELDS
{ ARGS [ RANGE=( start , end ) ] |
VARS={ output-vars-list | variable * }
[ RANGE=( start , end ) ] }
FROM
MDO= variable-name
If the MDO operand specifies an element that has no defined groups or fields, then no
data is returned. If the MDO operand specifies a group name, only those fields
defined within that group are returned. If the MDO operand specifies a group that
contains no further fields, or a single field name, then no data is returned.
