Since your mail reader does not understand this format, some or all of this message may not be legible. -- [ Picked text/plain from multipart/alternative ] I am very curious about this as well because I created a SRVPGM with a file and didn't specify USROPN (and didn't do any explicit OPENs or CLOSEs). I also didn't seton LR when exiting the SRVPGM (leaving the files open) and this caused problems - I don't recall the exact message but it was an MCH message and it indicated that the SRVPGM (or resources) was destroyed. So, I changed the program to USROPN and explicitly OPENed the file upon entry into the SRVPGM and explicitly CLOSEed it after using it. I don't like doing this because it burns more CPU time but it took care of the problem.

(Because it have no RPG cycle embedded) But it does, during first call. I've checked it.

Service program do not have an RPG Cycle embedded in them. The ability to use the OPEN and CLOSE operation codes has nothing to do with the USROPN keyword. A file could be opened outside of the program or in your case, Service program.
