actionscript 1 to actionscript 3 conversion

[puratu]

hi
I am trying to convert this code from as1 to as3
any help would be appreciated
occ = ((dec=new String("000000").substr(0,7-(dec=(unescape(map[0]).charAt(int(i/7)).charCodeAt(0)-1).toString(2)).length)+dec).charAt(i%7)==1);

ok i had a go, but there are other variables in the algorithm which I have no idea what they are for. so can you show some of the previous code and explain what this code is meant to do please?

sth like this

(o = this.createEmptyMovieClip( "point" , 0 )).lineStyle(7,0xffcc00)
o.moveTo(4,4)
o.lineTo(4.5,4);
map= new String("%C2%80%C2%80%C2%80%C2%80A%02A%02%5F%7E%60%3ESFR%26%5F%7E%60%3EA%01%01%02%5Fp%7C%3E%5Fp%7C%3EAbD%02%7F%7E%60%40%03%7E%60%21%03a%04%21%03o%3C%21%7Fo%3C%40%01%0D%19%01%7Fp%7C%40%03p%7C%21%03a%04%21%03p%7C%21%7Fp%7C%40A%02A%02%5F%7E%60%3E%5F%7E%60%3EG%01%012wp%7C8wp%7C8AbD%02%60%7E%60%7E%60%7E%60%7EA%01%01%02%C2%80%C2%80%C2%80%C2%80,%01%01%01%01%40%7F%40%7F%22%03%21C%22%03%21C%22%03%21C%40%C2%80%C2%80%7F%22%11%05C%22%11%05C%40%1F%3D%7F%02%01%01A%02%01%01A%02%01%01A%02%01%01A%02%01%01A%02%01%01A%02%01%01A%02%01%01A%02%01%01A%02%01%01A%02%01%01A%40%7F%40%7F%22%03%21C%22%03%21C%3A%7F%40O%0A%11%05I%0A%11%05I%40%1F%3D%7F%21%03%21%03%21%03%21%03%40%C2%80%C2%80%7F%01%01%01%01").split(",");
