Just in case someone cares, since I don't know perl, in python it would be written as var[x:y] and is called a "slice". The same can be done with other sequence types such as lists and tuples. If you use only one index (and no ':') then it is a simple indexing like an array in C. Either endpoint can be omitted in which case the sequence's boundary is assumed. If either index is negative, it counts from the other end of the sequences. -D -- In the way of righteousness there is life; along that path is immortality. Proverbs 12:28 http://dman.ddts.net/~dman/
