Ok, How can append result value to array?

for i in 0:6 loop

v:=abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

end for;

Or just fill an array before the loop so you can assign each element (much faster; cat is expensive).

arr := fill(0.0, 6);

for ... loop

  arr[i] := ...;

end for;

    Thanks again
Oki

arr := fill(0.0,6);

for i in 0:6 loop

arr[i]:=abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

print arr[i];

end for;

print max(arr);

when run script i got; Error: Parse error: Only function call expressions may stand alone in an algorithm section
before use arr() i have to define or something?

I mean i know print only stdout,
When i try to write array to file i got nothing,

for i in 0:6 loop

arr[i]:= abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

end for;

writeFile("c:/loop/log.txt",String(arr[0])+"\n",append=true);

log.txt  is never create w/o any error. But for testing purposes i try;

for i in 0:6 loop

arr[i]:= abs(val(TABLO.y[1],i*1000)-val(vMetre.v,i*1000));

end for;

writeFile("c:/loop/log.txt",String(11)+"\n",append=true);

log.txt   created and inside data 11.
