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

  The REPLACE  command  writes  the  current  program  back  to  the  file
  specified  by  the  last  OLD  command.   BASIC  creates and saves a new
  version of the file, incrementing the version number by one  unless  you
  supply a specific version number with the OLD command.
