IIRC, LAP code is represented as a list (or is it a vector?) where each
instruction is represented by a symbol with some arguments.  So it's not
a textual representation, but it's a "symbolic" representation that's
fairly easy to manipulate and with many similarities to traditional
assembly: use of labels instead of actual addresses, use of
pseudo-instructions (e.g. labels), and things like that.
