AskAppend["key"]

is a construct for use inside AskFunction that asks for a new value, appends it to the current value associated with "key", and returns the resulting list.

AskAppend["key"formspec]

uses formspec to define how input should be requested and interpreted.

Details

  • If there is no value yet associated with "key", AskAppend will put the new value it obtains in a list.
  • Executing AskAppend again with the same key will append each new value to the list associated with the key.
  • If there is an existing value associated with "key" that was obtained from Ask, AskAppend will put this value in a list before appending a new value.

Using Ask before AskAppend will result in the first answer being wrapped in a list before appending the result:

Using Ask after AskAppend will result in the currently known list of values being returned without a form being presented:
