How do I use the Delete()-procedure from javascript ?
I have already tested, but i do not understand the Syntax "Delete(var s: String; from, count: Integer): String"
I want to delete the leftmost char from a given string .... but:
brings only the error message "Expression expected" !
Help..., Please.

Still grappling with replace in a string?
Try DeleteStr instead of Delete; works for me.

Must be an error in the Fast script documentation. I don't think anything is returned from the Delete function. It should be just
Code: Select all
var s = "My string";
Delete(s,1,3);

The code you propose triggers "Expression expected" error. It should be (as I mentioned above):
Code: Select all
var s = "My string";
DeleteStr(s,1,3);

OK. "Delete" is apparently an operator in JavaScript, so you have to use "DeleteStr" instead. "Delete" works fine in a Pascal script though.
