What i am trying to do is make an alias that will take a string and output the string with randomized color codes in it.

I pretty much have is complete except for a small problem i have with the special character "@".

here's the contents of a test alias i made to show what am trying to do




#var test1 {"!"|"@"|"#"}


#var string ""


#LOOP 1,%len( %0) {


 #var string %concat( @string, "`", %item( @test1, %random( @test1, %numitems( @test1))), %copy( %0, %repeatnum, 1))


  }


#echo -@string-

in this example everything works fine expect when the @ is choosen, which then causes it to use the @ and the next character in the string to lookup a varible which it don't want. I just want it to print the @ and then the next character in the string.

any help would be appreciated

check out the %expand() function. It's a powerful little doodad that allows you to control how much expansion occurs. Dunno if it'd be what you are looking for, but it's a start.

~@variable this prints the @ symbol instead of seeking it as a variable.. :-D

For tomarrow is another day, and other days come but 6 times a week.

Doesn't quite work when the special character is the value of a variable. Zugg already addressed this point in a previous point and told us we needed to use %expand().

Via %expand(), one can control the amount of expansion--from no expansion (I think) to just @ and % to something else to full expansion. Check the function reference for exact details
