Can anyone out there tell me whether there is any form of dynamic arrays
in Modula-2? Specifically, if it will only be known at run-time how large
a certain array needs to be (it is given as user input, or something), can
you do something like
PROCEDURE p(N:CARDINAL);
VAR x:ARRAY [0..N] OF ...blah...
and simply pass the required size of x as the parameter to p? I can find
nothing in Wirth or any other reference I can find saying that you cannot,
and the syntax allows it. It seems like such a common situation that I
cannot imagine that the language would prevent me from doing it, yet the
compiler I have barfs when I try (admittedly it is an experimental
compiler). So which is broken, the compiler or the language?
Thanks in advance for your help.
