Library /sys$common/syshlp/BASICHELP.HLB  —  Run time errors, MEMMANVIO
  Memory management violation (ERR=35)

  The program attempted to read or write to a memory location  to  which
  it was not allowed access.  If the program was compiled with /NOCHECK,
  it may be exceeding an array bound; recompile with /CHECK.  Otherwise,
  check  program logic.  This error cannot be trapped with a BASIC error
  handler.
