[fpc-pascal] Re: put data to stdout (fpc vs. gcc)

Hi Jonas,

It will break with an error from the library, if the procedure is to slow. The fpc-writeln()  works fine but to slow. The gcc-printf() works fine and fast.

Do you know a better way to produce a fast formated output in FreePascal.
I would use FreePascal and not gcc, but the fpc result is not practical.

C source:

for (i=0;i<n;i++) {
  out1=(single) libout1[i];
  out2=(single) libout2[i];
  count+=1;
  printf("%20.0f%15.5f%15.5f\n",count,out1,out2);}

fpc source:

for i:=0 to n do
begin
  out1:=single(libout1[i]);
  out2:=single(libout2[i]);
  inc(count);
  writeln(stdout, count:20, out1:15:5, out2:15:5); (* This will break! *)
end;
