Library /sys$common/syshlp/basichelp.hlb Commands, RENAME  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The RENAME command changes the name of the program currently in  memory.
  BASIC  does  not  write the renamed program to a file until you save the
  program with either the REPLACE or SAVE command.

  Example

  RENAME prog1

  Format

      RENAME [ file-spec ]
