I have a list that I need to remove the last three items from. The problem is, the items can be anything (text, numbers, special characters). Normally that wouldn't be a problem with the #delnitem command, but the list can be any number of items. There isn't really an effective way to count the number of items (the list is from a .txt file and changes constantly). Are there any ways to use pattern matching in the %replace or %remove functions, or anything similar? Something like this: #var matches %replace( @list, "^[alias-%-1] *$", "")

Any ideas?

You can count the number of items in the list by using %numitems. Thus, you can do this to remove the last three items:
#DELNITEM list %numitems(@list)
#DELNITEM list %numitems(@list)
#DELNITEM list %numitems(@list)

Would this work, too?

#LOOP 3 {#DELNITEM list %numitems(@list)}
