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

  INFORMATION   -   This   error   is    reported    only    when    the
  /FLAG=BP2COMPATIBILITY  qualifier  is  in  effect.   A  parameter list
  contains a BY clause which is  invalid  in  PDP-11  BASIC-PLUS-2,  for
  example,  specifying BY DESC for parameters that are not entire arrays
  or strings.  See the Compaq BASIC for OpenVMS Alpha  and  VAX  Systems
  Reference   Manual   for   allowable  BASIC-PLUS-2  parameter  passing
  mechanisms.
