I found a little problem when trying to use arrays of unknown sizes as
arguments in Draco's functions. I typed the example given in the doc,
which looks like that:
proc minimum([*] int t) int:
int min,i;
min := t[0];
for i from 1 to dim(t,1) do
if t[i] < min then min := t[i] fi
od;
min
corp;
The compiler returns the error 'cannot use sizeof on array with '*'' (or
something like that), and indicates
if t[i] < min then min := t[i] fi
^
If I replace i with a constant or a numeric, it works. Why does this
happen?

Why does this >happen? I tried the source from this article, and got a complaint about syntax (it should be 'upto' in the 'for', not 'to'), but after fixing that, it compiled fine. Can you mail me the exact routine that is failing? I used my V1.3 beta version of the compiler, but my log files going back to Jan 88 show no changes that could have fixed a bug like that. Also, since Draco arrays are 0 origin (same as C's), the 'for' loop should be: for i from 0 upto dim(t, 1) - 1 do ... od; If all else fails, I can uuencode and mail you V1.3. (I haven't released it yet since I want to do a whole new set of documentation.) -- -- Chris Gray usenet: {uunet,alberta}!myrias!ami-cg!cg CIS: 74007,1165
