RTVDTAARA in as 400

The Retrieve Data Area (RTVDTAARA) command is used in a CL program or REXX procedure to retrieve all or part of a specified data area and copy it into a variable. RTVDTAARA does not retrieve any other attributes of the data area. Existence of the data area is not required at the time the CL program is compiled.
