Hi,
The following Algol program used to work in DrRacket with the language Algol
60 selected.
begin
integer i;
real procedure sum(j, lo, hi, term);
value lo, hi;
integer j, lo, hi;
real term;
comment term is passed by-name;
begin
real temp;
temp := 0;
for j := lo step 1 until hi do
temp := temp + term;
sum := temp
end;
i := 1;
printnln(sum(i, 1, 100, i))
end
Now it gives the following error.
for-body96339: unbound identifier;
also, no #%top syntax transformer is bound in: for-body96339
Has something changed? It does seem to work in Racket with a #lang
directive, and simpler Algol 60 programs do work in Algol 60 mode. Why
should this be?
Thanks.
-Arthur
