This topic describes the two ways to rename a member: STOW and DESERV RENAME. DESERV RENAME only supports PDSEs but it supports names longer than 8 characters.
With DESERV RENAME, it is possible to define a list of PDSE member names (primary and alias) that are to be renamed. The DESL_OLD_NAME_PTR fields of the DESL array are used to point to the names which are to be renamed. The associated DESL_NAME_PTR fields are used to point to the new names. The RENAME function requires the caller to pass a DCB open for output or update. The renames are processed in DESL sequence. Codes in the DESL indicate whether the rename was successful for each entry in the list.
