A great technical repair 1 is to use set with the /P parameter to avoid line wrapping.

The following two batches produce the desired effect:

@echo off
for /L %%a in (1,1,3)DO echo|set /p="%%a "

and

@echo off
for /L %%a in (1,1,3)DO <nul set /p="%%a "

The /p is usually used for input with a prompt , so it does not break any lines. Combining the input with an artificial input, which comes from a echo with pipe in the first example and a nul instead of stdin of the second, we have the effect of showing the prompt without breaking lines, and without waiting for the input .

The second option apparently has a higher performance, which can be evaluated with more extensive tests (larger loops, for example).
