1. null as a valid data
Robert, can you introduce null as a valid data, so that the following would
work?:
-- program
sequence string, test
global procedure testchars
atom nulltestchar
if ( string[24] = 'f' ) then
test = dosomething(string[22])
end if
test = dosomething(atom)
end procedure -- testchars
function dosomething(sequence data)
if ( data != null ) then puts(1,data&CRLF) end if
end function -- dosomething
string = "this is 21 chars long"
testchars
-- end program

Just create your own atom null and set it equal to 0. If you are reading =
bytes from an input stream or a binary file, C-style strings are standardly=
terminated with #00.

And how will that solve the examples i gave?
