Subject: Iterate over md Array (the Ruby way)

Hi all,

Once again I disturb you for a, maybe, obvious thing
I can't figure out.

I have successfully created an md array (see older posts
from me) thanks to the support found here.

Now I would like to list all String items in the source array
(a Text file containing numbers) and convert and place them into the 
destination array as int objs. I know about the String#split method but 
this recreates an array that does not match the dimensions I want
(e.g. lines with different length).

My approach is very c-ish:

<code>
# @source is a String array. If the string contains a non-convertible
# substring, 0 is placed in destination array. @array is the destination 
# md array created with the appropriate dimensions according to @source 
# (longest line as vindex (-) and index as hindex (|) )

for i in 0...@hindex.length
	for j in 0...@vindex[i].length
		@array[i][j] = @source[i][j].to_i.char.to_i
	end
end
</code>

Is there a Ruby way to replace <code> with blocks?

Thank you very much for a hint.

Brgds,
Peter
