[HECnet] RSTS/E 10.1 BASIC-2-PLUS problem

[Keith Halewood]

Thanks Johnny,

It’s [1,2]bp2rfa.hlp and its protection was 48. I’ve set it to 40 and a non-privileged, non [1,*] account can now see help in the basic-2-plus env.
The whole RSTS/E V10.1 and BASIC-2-PLUS installations are entirely default. Apart from adding DECNET/E and enabling LAT etc., nothing else should be other than default.
Weird.

Thanks again

Keith

All that said - if the op is actually using basic+2 then help is a builtin command in the interactive environment. Furthermore the basic+2 builtin help uses an extra file for fast lookups into the help file, so this additional file could also be the problem.

I'd need to check when I'm back home what the exact name of this file is, but something like bp2hlp.rfa maybe?

Command processing in RSTS depends on which runtime system (more precisely, "keyboard monitor") you're currently in.

If you're in DCL, standard DCL commands (like "copy") are understood.  "help" is another standard DCL command.

In most other runtime systems, like BASIC, there are a few built-in commands that relate more to the purpose of that runtime system (like "SAVE" or "OLD").

In addition, keyboard monitors normally understand any of the defined "system commands" -- also called "CCL commands".   Those are commands defined via the create command/system DCL operation, and you can see them with show command/system.  For example:

$ show com/sys
BCK-       =  SY:[  0,10 ]RMSBCK.TSK /LINE=0
BYE-       =  SY:[  1,2  ]LOGOUT.TSK /LINE=0    /PRIVILEGE
CNV-       =  SY:[  0,10 ]RMSCNV.TSK /LINE=0
DI-RECTORY =  SY:[  1,2  ]DIRECT.TSK /LINE=CCL  /PRIVILEGE
...

In my system, "help" is not shown there, so while DCL knows it, other RTS would not.  If your system does respond to it, what is the command definition?

As for [0,2]help.tsk, that's a strange protection code.  Mine has <104> and I can see no reason why that program should be privileged.

Hi Paul,

Thanks for the info. Other than help.hlp, there is only help.tsk in [0,2] and it has protection <232> (privileged, execute, world readonly, group+owner read/write)
After a backup, I’ll do some further experimentation.

Regards

Keith

Hi,

I’ve been playing with RSTS/E for a short while, particularly BASIC PLUS. I’ve noted that, logged into account [1,2] I can issue HELP from within BASIC and it’s all fine. From a non-privileged account I created, HELP within BASIC gives me a ‘?Protection violation’ but it seems that all the .HLP files relevant to BASIC have the correct <40> file protection. Am I missing something? Any help would be appreciated.

Regards,

Keith

"help" is most likely a CCL command -- a command defined, typically at startup, that is handled by executing a program.

You're right that the actual content in in the *.hlp files, and they need to be protected <40> for that to work.  But in addition, the program that handles the command has to be executable by non-privileged users.  So look in [0,*] or [1,2] for a help.* file (help.tsk, help.bac, help.sav perhaps).  It has to be executable (64 bit set in the protection code).  So a typical protection code would be 104.
