[Solved] Some questions regarding dynamic arrays.

| Hello all! I'm reading in a large textfile into a dynamic string array and split it linewise. A. Is there a way to determine the number of array elements without having to go through all of them step by step? B. Is it possible to delete the very last element of the array? In my case it's always an empty line / data element and I don't want to check for it every time. Example code
Local line_counter:Int=0
Local l:String
Local k:String[] = LoadText("mytext.txr").split("~n")
For l:String = EachIn k
If l <> "" Then line_counter=line_counter+1
Next
I'm looking for some basic tweaks, perhaps there's a smarter way of doing this. ;) Thanks! Grisu |

| Hiya, A. You can use the '.length' member of arrays. So you would have For i:Int = 0 Until k.length
Local l:String = k[i]Don't forget that arrays are 0 indexed - you would need to iterate from 0 to array.length - 1, or use Until as above. B. Using the array length above is it ok to just ignore that last element? with k.length - 1 or '- whatever' as needed. |

| Thank you Dave. Works fine and saves some ms. |

| Hi, just for fun, Array "AddLast" method: array = array[..array.length + 1] array[array.length - 1] = "New value" 'Assuming array is of strings Array "DeleteLast" method: array = array[..array.length - 1] -Henri |
