Crystal Report formula issue :How to split multi line text value in to the array and how to fetch it by forloop in - crystal-reports

Question

I have one field in a dataset which has a multi-line textbox value. I want to split that record, store it into an array, and when I fetch the value from the array by a for-loop, I want to prepend a "*" to each line. I have written a formula for that but it's working only for 2 values. After that it's not working and I'm not able to get how to retrieve the value like this.
I want the result to be:
* 123
* 234
* 786
But I'm getting the result:
*123
234
786
my formula is
Local StringVar y;
Local StringVar x;
Local NumberVar i;
y := ""+ chrw(10);
x := y;
Stringvar Array strings := Split({Touche.Concerns}, "\r\n");
Stringvar Array numbers;
For i :=1 To Ubound(strings) Do
(
y := y + chrw(10)+ "$" + strings[i];
);
y;

Answer 1

Instead of a long formula which breaks into arrays and manipulates each line, why not just replace the line breaks with a line break and the asterisk?
"* " & replace(trim({Touche.Concerns}), "\r\n", "\r\n* ");
The leading '*' is to place the char on the first line and the trim function is called to remove any trailing line breaks (so there won't be a line with just the asterisk).
As a side note, use & when concatenating strings and not the + char. Use the + can sometimes cause coercion to where numeric values would be added together. For example "12" + "34" would yield 46 instead of 1234. The & char ensures string concatenation is used.
