I agree that Browse isn't supposed to require enough memory to hold the file, so it should work.
But. Is "compressed data" the key? How is it compressed? Does the fact that it is compressed mean that more data has to be in memory? Or is it going wild on decompression, such as if the data is corrupted so the length is wrong? (Like how it is possible to create a tiny .ZIP file that decompresses to terabytes.) -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Farley, Peter Sent: Tuesday, May 23, 2023 3:13 PM To: [email protected] Subject: Why does ISPF BROWSE abend with S878 searching a large sequential file? This has happened to me twice this afternoon, and several other times in the last few months - I am trying to browse (from ISPF 3.4) a quite large sequential file (> 14500 cylinders of compressed data) for a record with a specific 31-byte key at the beginning of the record, and browse abends with S878 and throws me off TSO entirely, requiring me to login again each time. My TSO logon region size is set to 48000, so what in the world is making browse consume so much memory that it runs out and crashes my TSO session entirely? I know, OCO prevents anyone knowing for sure, but if you have any clue I'd appreciate knowing the answer. I've been forced to search that file using SORT in a batch job to keep the frustration level lower.
