I have legacy code from Borland C++ v5.xx that usese
the format:
printf("\n\rheader of information\n\r");
while(ok) {
printf(\r%6i itterations", ii++);
...
}
I get a CR/LF for the \r output.
Instead of a CR only.
Using DMC v8.29n "-mtd" compile to .com option.
Any help appreciated

stdout->_flag |= _F_BIN;

problem in coding.
ran simple test to confirm both LF & CR/LF output.
worked as expected.
re-examined original code.
I was outputing a line >80 characters so line would wrap to newline.
re-worked the printf to output less than 80 characters, expected output.
Thanks for the quick response.
details of printf and change..
printf("\r%7s%9s %6u %-64s" , cItemREF, cItemSAN, iItemNum,
cItemDes); }
changed to:
printf("\r%7s%9s %6u %-32.32s" , cItemREF, cItemSAN, iItemNum,
cItemDes); }
original printf sent space-padded text beyond column 80; force stdio to wrap
to newline.
corrected printf limits the line to less than 80 to get expected results.
