copied!<p>Let me introduce you to my friend, the <a href="http://ss64.com/nt/for.html" rel="nofollow">for loop</a>. Save all the lines the user entered into a single file. I'll call this file <code>input.txt</code>. Use a <code>for</code> loop with the <code>/f</code> switch and the <code>delims=</code> option to loop through every line in the file, and store the lines in the variable <code>%%i</code>. Without <code>delims=</code>, it'd read only until the first whitespace character.</p> <p>For each line it reads, do your text substitution. The "gotcha" with batch programming is when you set variables inside a <code>for</code> loop, you have to add the line <code>setlocal enabledelayedexpansion</code> at the top of your file, and use <code>!</code> instead of <code>%</code> to access the variable contents.</p> <pre><code>@echo off setlocal enabledelayedexpansion for /f "delims=" %%i in (input.txt) do ( echo translating "%%i"... ^<insert fake delay here^> set var=%%i set var=!var:a=1 ! set var=!var:b=2 ! set var=!var:c=3 ! set var=!var:d=4 ! set var=!var:e=5 ! set var=!var:f=6 ! set var=!var:g=7 ! set var=!var:h=8 ! set var=!var:i=9 ! set var=!var:j=10 ! set var=!var:k=11 ! set var=!var:l=12 ! set var=!var:m=13 ! set var=!var:n=14 ! set var=!var:o=15 ! set var=!var:p=16 ! set var=!var:q=17 ! set var=!var:r=18 ! set var=!var:s=19 ! set var=!var:t=20 ! set var=!var:u=21 ! set var=!var:v=22 ! set var=!var:w=23 ! set var=!var:x=24 ! set var=!var:y=25 ! set var=!var:z=26 ! echo !var! ) </code></pre> <p>If <code>input.txt</code> has these contents:</p> <pre><code>programable this is line 2 third line </code></pre> <p>Then the output would look like this:</p> <pre><code>C:\batch>encode.cmd translating "programable"... <insert fake delay here> 16 18 15 7 18 1 13 1 2 12 5 translating "this is line 2"... <insert fake delay here> 20 8 9 19 9 19 12 9 14 5 2 translating "third line"... <insert fake delay here> 20 8 9 18 4 12 9 14 5 </code></pre> <p>As you can see, I left out the fake delay. I like my programs fast. :)</p>
