Re^2: print on one line

It is true that the -l switch is not needed. Nor is $\="" needed since there is no input. Removing both will still output horizontal asterisks.

However, -w will not affect the output with respect to horizontal or vertical; it enables warnings. See perlrun.

Exactly, and that's why I recommended it. -l is not needed, so I suggested to remove it. -w is recommendet, so I suggested to add it. If you remove l and add w, you can equally say that you replace l by w ;-) -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]
