IOBUF=yyyKCoding the run-time interface parametersAfter you set the amount of memory, code the following run-time parametersin any order. The last two interact with each other. To see the results of theirpossible combinations, see “Results of different combinations of SPIE andDUMP” on page 25. Follow the coding recommendations to avoid difficulty.Z/OS This parameter indicates the amount of storage to return to z/OS for I/Obuffers and control blocks after the STACK value is allocated. Since little of thefunction's I/O uses this storage, the 36K default is sufficient.TIP We recommend not coding this parameter.STACK=xxxKThis parameter sets the amount of storage for the run-time stack/heap. TheExtract needs at least 400K. If you do not code this parameter, the default isthe entire region.You will want to leave room in your region for loading other programs, such asthe PDM or an exit program, so Cincom recommends that you always code thisparameter.SPIE/NOSPIEFor further information and recommended values, see “Setting the z/OS STACKparameter” on page 26.This parameter indicates whether the run-time interface should interceptprogram checks by the operating system.The default is SPIE, however, Cincom recommends coding NOSPIE (notintercept them).DUMP/NODUMP You can use this parameter to indicate whether you want a dump of theaddress space in z/OS. This parameter determines whether you get a dumpwhen:♦♦The run-time interface intercepts a program check. If you coded NOSPIE,the run-time interface does not catch a program check and the operatingsystem creates a dump.A run-time error occurs. If a run-time error occurs, you do not need adump. The default is DUMP, however, Cincom recommends codingNODUMP.Extract Utility User's Guide, P25-9513-03 24Chapter: 3. Executing the Extract utilitySection: Choosing run-time options in z/OS
