Hi so I've got a string and I've got a variable that contains the position of different messages from the string. How could I delete the lines I got in the variable?

If it is a string array, and you want to remove a portion of a string in the array consider using eraseBetween:
If you have an array where each row contains a string, and you just want to remove entire rows, use indexing to set those rows equal to [].
myStr(rmvPositions) = [];

Are you looking for something like this?
str = ["line 1";"line 2";"line 3";"line 4";"line 5"]
str = 5×1 string array
"line 1" "line 2" "line 3" "line 4" "line 5"
var = [2 3];
str = 3×1 string array
"line 1" "line 4" "line 5"
