//echo $replace(this is just an example,a,b,b,c,c,d,d,e,e,f,f,g,g,h,h,i,i,j,j,k,k,l,l,m,m,n,n,o,o,p,p,q,q,r,r,s,s,t,t,u,u,v,v,w,w,x,x,y,y,z,z,a) all this does is returns all a's. (aaaa aa aaaa aa aaaaaaa) I don't want replace to work progressively, I want it to turn all of the original a's into b's, and all of the original b's into c's. Right now it's turning all of the a's into b's, then every b (including the a's that were turned into b's) into c's, and so on and so forth. This is pointless and annoying.  Does anyone know of any workaround? -edit I sure hope I don't have to go letter by letter..

That is the way $replace has always worked, from left to right.

Then change the replace order...

That doesn't make sense.. Whatever order I use will still end with skewed results. I'd have to go character by character, and that is extremely CPU intensive.
The workaround I've managed is to use $replacecs with only lower-case letters for input, replacing letters with uppercase ones, then converting the output back to lowercase, but I'd really rather create a better script than this that also utilizes a minimum amount of CPU processes..

I hate this too. Well, strongly dislike. Maybe something like the below would be a good feature suggestion.
$replace(string,substring,newstring,N) where if N equals 1 if it the way it works now. If N equals 2 it will not modify any newstring additions.

or $replace(string,substring,newstring,substring,newstring).npr where npr stands for non-progressive.

A property for $replace to behave like that would be nice. If all you want to do is replace single characters like that though then the scripted version is quite simple really: char_replace {
; Usage: $char_replace(string,char,newchar,...,charN,newcharN)
var %i = 2, %j = 3, %c = 1
bset -t &string 1 $1
while $eval($+($,%j),2) != $null {
bset &chars %c $asc($eval($+($,%i),2)) $asc($ifmatch)
inc %i 2
inc %j 2
inc %c 2
}
breplace &string [ $bvar(&chars,1-) ]
return $bvar(&string,1-).text
}echoes uijt jt kvtu bo fybnqmfRemember that only works for replacing single characters though.

actually /breplace is non-progressive like this, and is a lot faster than your loop.
The only exception is that /breplace can only handle single-byte (character) replacements, and is not useful if you want to replace letter pairs or words with other words.
For this use however, /breplace is the breakfast of champions.
Well. At least I won lunch.
Good philosophy, see good in bad, I like!

Yes I know /breplace behaves like that, that's why I used it in my alias. The loop is there so that the parameters can be given as characters instead of ASCII codes.
