; Remember "userfield" is not a token that you can replace with an identifier of your choice
; it is a constant.

  exten => s,n,Set(CDR(userfield)=bling blong blang)
;
; Stores "bling blong blang" in untagged field at the end of the CDR in

333All fields except userfield and account code are read only!

Turns out you can't use Set(CDR(<name>)=value) for anything but userfield and accountcode.
These fields are read-only.

Also (mr picky!), "astapp" above of course should be 'lastapp'.
