It also depends on the DFSORT-specific controls you put in place - as Dave Betten former keeper of the controls (currently on vacation) will tell you.

I'm not DFSORT folk, but I think, I can explain it. Some time ago I was fighting with some job consuming to much memory. First I limited its storage with MEMLIMIT, but then DFSORT started using *spaces instead. Still a lot of memory. The conclusion is simple: DFSORT use any of the memory kind which is available, with some preferences of course. Details depend on availability or given resources. -- Radoslaw Skorupka Lodz, Poland -- Tre tej wiadomoci moe zawiera informacje prawnie chronione Banku przeznaczone wycznie do uytku subowego adresata.
