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

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.

"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.
