It appears to be the RPG/C job. If you do TRCJOB for a pgm that reads a streamfile, it appears that procedure lookupIt__Qp0dDiropLookupFv in srvpgm QP0FEPFS issues an SVC to call SLIC module #P0DLOOK, which does the lookup. Since it's done in SLIC, I don't know whether any MI cursor is involved, or whether it reads the DSI directly. It appears that this lookup occurs only once and the info is put in a system-wide cache, because if you call the pgm a 2nd time, even in another job, you don't see the call to lookupIt. But anyway, it appears to be done in the RPG/C job. --Dave On Monday 07 January 2002 08:10, Gene_Gaunt@ReviewWorks.com wrote: > When an RPG or C program reads through IFS directory entries, does the job > running the RPG or C program actually own and work the MI cursor over the > MI data space index, or does another "service" job do that?
