RE: SETLL on a multiple record format Logical file

is it by any chance a multi-member logical? In that case, I'm afraid, what
you are looking for can't be done. Everything is fine when RPG knows what
access path to use for SETLL. And it definitely does work with multi-format
single member logicals. Becasue they have only one access path. If, on the
other hand, there are multiple members/multiple access paths and by using
SETLL with just the file name you provide RPG with no information of what
access path to use, RPG fails. It does not report a problem, but processes
only one of the access paths - I've never been able to figure out what
algorythm is used to determine the name of the access path to process. Maybe
it's just the last used.
