If I put the .lgs file on the IFS, how do I define it and read it

period. What is confusing is that when I open the PC file with
notepad or a Hex editor, I can set the length to 16 or 32 bytes,
etc. When it copies to the IFS, how then may I read it and what
would be the record length to use?

You wouldn't use an F-spec. You'd use the stream file APIs, as
described by Scott Klement at

It only looks hard. If I can do it, anybody can!

And FWiW: If the data from the .lgs file is put "on the IFS" into a user space (*USRSPC) object under the /QSYS.LIB file system, then the data can be processed as a stream without any [stream] file APIs; using the Retrieve Pointer to User Space (QUSPTRUS) API and pointer-based addressing or the Retrieve User Space (QUSRTVUS) API if not using pointers:
