To avoid the insertion of a carriage return you could use
*WriteString["stdout", "text_to_be_on_a_same_line"]*.
Also, *PrintTemporary[]*, which automatically discards the generated
cells when the evaluation is done, might be an option, as well as
*Monitor[]*.
Here are examples of each of these solutions.
Do[If[Mod[i, 10] == 0, WriteString["stdout", " Step " <> ToString[ i]];
Pause[.2]], {i, 50}]
Step 10 Step 20 Step 30 Step 40 Step 50
Do[If[Mod[i, 10] == 0, PrintTemporary["Step " <> ToString[ i]];
Pause[.2]], {i, 50}]
Monitor[Do[If[Mod[i, 10] == 0, cnt = i; Pause[.2]], {i, 50}], cnt]
Hope this helps,
