[Cst-1b] Comp.Prog.Lang - ALGOL - Trouble Spots 2

[Martin Harper]

On page 16 of comp.prog.lang(5.8), one of the trouble spots of ALGOL is claimed
to be -
"The types and modes of calling procedure arguments could not be specified."

however, looking at the code fragments, it seems that you can - for example,
over the page there is a "transpose" procedure, which runs as -

real procedure transpose(A, m)
    value m;
    real array A; integer m;
begin
    ...
end

this clearly implies to me that the mode of calling is that m is by val, A by
name, and that m is an integer, while A is a real array.... what have I
forgotten/misunderstood? :(
