I´m working in a script which removes some randoms letter of a string.

If I have a string like: "I like my blue umbrella", How can I remove some letters from this string?
For example, if my randoms are 4,6,11, the string should be: "I l k my lue umbrella", the removed letters should show blank spaces.

Any idea how to do this?

Yes, I have manipulated strings a lot, but I don´t have idea how to do this.

I can use STRSUB to get a letter in a string, but I don´t know if is it possible to set a letter in a string. So my question.

well, if you cannot put random blankspaces in a string, do the opposite and write a new string picking just some letters from the previous one. A simple loop can do the job. ^^

I would do the following:

generate a random number between 0 and string length-1.

get a substring of the random number. Store that somewhere.

then get a random number between last random number + 1 and string length-1.

get a substring of random number + 1 -> new random. and concatenante that to the last stored substring.

repeat that step again and you will have joined 3 substrings, which should have cut off 1 character following the value of the random number that was picked.


if that makes sense

Humm, thats is a good idea. I´ll try that.
