1. A computer-implemented method of facilitating processing in a computing environment, said computer-implemented method comprising:

  • detecting an abort of a transaction based on a guarded storage event; and

    processing, by at least one processor, the guarded storage event, based on detecting the abort of the transaction based on the guarded storage event, wherein the processing the guarded storage event includes;

    determining whether the guarded storage event still exists, and wherein the determining whether the guarded storage event still exists comprises;

    refetching a selected operand of an instruction causing the guarded storage event; and

    using the selected operand to determine whether the guarded storage event still exists; and

    continuing with processing of the guarded storage event based on determining the guarded storage event still exists.
