Showing characters in user input?

[Adrianvdh]

Hello everyone...

I need some help...

If I were to add a user input variable and the user enters "3"

how would I make a function to echo the character "-" 3 times

Input:
3
Output:
---

Thanks for all your help and your time

Open up a cmd promt and type: FOR /?
Read the section about using the /L option.

Hi, sorry I am struggling a lot here with the "for /l" command

This is what I have so far...

Code: Select all

for /l %a in (1,1,52) do echo -

Thank you for your help, if you can help me

FOR /L is only midway. The second half is how you would print it in one line.
Imho two possibilities.

1st create a variable

Code: Select all

set /p "n=Number: "
setlocal EnableDelayedExpansion
set "hyphens="
for /l %%i in (1 1 %n%) do set "hyphens=!hyphens!-"
endlocal &set "hyphens=%hyphens%"
echo %hyphens%

2nd use the SET /P trick to display text without linebreak.

Code: Select all

set /p "n=Number: "
for /l %%i in (1 1 %n%) do <nul set /p "=-"
echo(

I guess your are right. I shouldn't have assumed the user knew how to use the set command. Figured they knew how from all the other scripts that have been given to them.
