How can I append items to a csh list?

Question

I would like to create a list that will contain strings that apply to certain conditions in csh.

How do I add to a list or array in a dynamic way without pre determining the size of the list or the array ?

Is there is list.add or some such in the c shell ?

Thanks

Solution

You can just use the form of set my_list = ( $my_list more ). For example:

# Create original list
% set my_list = ( hello world )
% echo $my_list
hello world

# Append to the list
% set my_list = ( $my_list hey there )
% echo $my_list
hello world hey there

# Loop over the list to verify it does what we expect it to do
% foreach item ($my_list)
foreach? echo "-> $item"
foreach? end
-> hello
-> world
-> hey
-> there
