Confused about 1st RSX11M

And by that I mean the startup of the disks I got from rsx11m.com. Startup ends at “>@ <EOF>”, seen below. So I assumed it was up and ready for you to logon. But when I tried as you can see it replied “LOG — Other User Logged On”. After awhile I realized I was already logged on because it responded to my “DIR” command. I could if I wish type “Bye” and logon somewhere else.

Here are a few of the ending startup messages…

>; PRINT PLOT:=MAP.HPG
>;
>; INSTALL TCP/IP
>;
>SET /NAMED
>SET /UIC=[1,2]
>* Load TCP/IP? [Y/N D:Y T:15S]: N
>@ <EOF>
>LOG
LOG -- Other User Logged On
>DIR

After startup…Where am I?

After I first startup it seems to imply that I’m in [1,2]. Also what is DU0:[200200]…NOT[200,200] But if I logout and log in to SYSTEM it says I’m in [1,1]…DU0:[1,1]

I was interested in these disks because I read that F77, BasicPlus2, C, APL, Pascal, COBOL were installed.

I typed SAVE and apparently it saved it as PROGRAM.BAS. But in my limited playing I couldn’t figure out how to load it back in to work on it more.

I typed HELP BASIC, and found I could type BP2…which is different than BASIC. This is more like what I am used to. This program was invalid under BASIC
