This is documentation for Mathematica 3, which was
based on an earlier version of the Wolfram Language.

  • MemoryConstrained[ expr , b ] evaluates expr, stopping if more than b bytes of memory are requested.
  • MemoryConstrained[ expr , b , failexpr ] returns failexpr if the memory constraint is not met.
  • MemoryConstrained generates an interrupt to stop the evaluation of expr if the amount of additional memory requested during the evaluation of expr exceeds b bytes.
  • MemoryConstrained evaluates failexpr only if the evaluation is aborted.
  • MemoryConstrained returns $Aborted if the evaluation is aborted and no failexpr is specified.
  • Aborts generated by MemoryConstrained are treated just like those generated by Abort, and can thus be overruled by AbortProtect.
  • See the Mathematica book: Section 2.13.4.
  • See also: TimeConstrained, MaxMemoryUsed, $RecursionLimit, Abort.

    Further Examples

    Here is an expression that would take a lot of memory to evaluate. The constraint stops the computation and returns the string.
