We could use double-buffering in S/3 RPG II. And S/38 blocking was enabled by the compiler for sequential input (like input primary) but sometimes the runtime wasn't as efficient as we wanted so we used OVRDBF SEQONLY(*YES nnn) and specified the number of records we wanted 'pre-fetched'. > IIRC, BLOCK(*YES) was available for the first release >of the OS for the System/38. Maybe some of the other >greybeards can confirm this. For the F-specification BLOCK(*YES), it's in my V4R4 RPG IV reference manual. For OVRDBF, it's in the first release of CPF. --buck
