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

  Maximum memory exceeded (ERR=126)

  The program has insufficient string and I/O buffer space  because  its
  allowable memory size has been exceeded or the system's maximum memory
  capacity has been reached.  Reduce the amount of string or I/O  buffer
  space or split the program into two or more modules.
