This environment variable forces the user account name to be stored as part of the saved list identifier.
As per normal environment variable.
JBCLISTID=1 export JBCLISTID
Lists stored in jBASEWORK have an id of the form SEL*UserName*ListName unless there is a Q-pointer or F-pointer called POINTER-FILE that references jBASEWORK.
If JBCLISTFILE is not set but POINTER-FILE can be opened, then lists are stored in POINTER-FILE and have have an item-id of ListName.
Otherwise lists have an id of the form ListName unless JBCLISTID=1, in which case the item id is SEL*UserName*ListName. Note that on Windows asterisks cannot be part of file names. So if JBCLISTFILE points to a directory, the asterisk separator is represented as ]2a.
