Hi.

Is there a short solution for this?

Even better:
DVArray=( $(seq 203 300) )

amigo; That`s a loop method I`ve never seen before.

I`ve got to go back and study the new Bash version docs.

seaside; Thanks for the info. Now I really need to do a refresher...

I was surprised to find that the for loop will read a file directly!

This loop: echo "$List" |while read Line ;do ... ;done
Still has an advantage or two.

It looks like the question asked was solved, but it is possible that it may not have been the right question. There are often better ways of handling arrays of sequential info depending on the context, by just using a few variables. (arrays are bashisms btw)... so the shorter solution could be not to use an array.

Ex. use:
starting_point, end_point, step
or
offset, increment_by, max_value

Which often need to be setup in the loops in some hacky way around the array anyways ... usually with an offset and/or max and step value.
