Deleting elements from a block
[1/3] from: learned::talentsinc::net at: 26-Sep-2001 13:29
Thanks for the assist on the CSV all, I actually managed it by just
appending a comma to each element before writing the block to a file
(deleting the tail of course). I am quickly learning to love this language.
One more question though. If I have a block of say 4 elements, how can I
delete JUST the 3rd element?

Remove operates on the current position in the series. To specify that, you
can use at.
>> tmp: [1 2 3 4]
== [1 2 3 4]
>> remove at tmp 3
== [4]
>> tmp
== [1 2 4]
Make note, also, of what is returned to you when you use remove.
