96	Make ring-1 initializer commands pass correct argument lengths. (MCR10037)	Gary Dixon	Gary Dixon	"A ring-1 initializer command, such as:

 reload_volume -pvdv root2 dska_03b -operator xxx -sys

fails in reload_volume, saying device dska_03b cannot be found.  This problem occurs because ring-1
command level calls a fixed set of commands, with small set of arguments.  In a limited user environment,
it uses a small, built-in command processor instead of using the full Multics ring-4 command processor.
This limited CP in system_startup_ always passes arguments as char(32), with each argument passed with 
blanks.  This works in many cases, since PL/1 string comparison treats ""ABC"" as equal to ""ABC   "".  
However, commands that check only the length of the input argument get invalid length data, since the
length includes the trailing spaces.  Instead, system_startup_ should calculate the length of each arg
passed, and put the correct length in the arg_list structure.

I'm calling this a Hardcore bug, because it affects system operation at ring-1, which it part of the 
hardcore administrative realm.  Also, system_startup_ is on the MST.
