The instruction is configured to perform a function, which is to be performed in a plurality of processing phases. A processing phase is defined to store up to a selected amount of data. A determination is made as to whether a store into a designated area occurred based on processing a select processing phase of the function. Based on determining that the store into the designated area occurred, an interrupt is presented. ## Claims ### Claim 1 A computer program product for facilitating processing within a computing environment, the computer program product comprising: one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media to perform a method comprising: performing instruction processing for an instruction, the instruction configured to perform a function, the function to be performed in a plurality of processing phases, wherein a processing phase of the plurality of processing phases is defined to store up to a select amount of data;
