Delete Items by Value (Added in SenseTalk 2.04)

You can delete items by value, rather than by their position. This is done using an each expression, which can be used to delete items in a list or any text chunk type (lines, words, items, or characters). A where, which, or whose clause selects the specific values to be deleted.

Examples:

delete each item of scores which is less than or equal to zero

delete each line of file "entries" which is empty

delete each item of subscriberList whose expirationDate is earlier than yesterday

Delete Reference

When a variable is set as a reference to a chunk of another value, the delete command can be used to directly delete that chunk.

repeat with each num in numbers by reference
if num is an odd number then delete num
end repeat
put numbers —> [2,4,6,8]
