with Lonely Hearts
up the procedures and try out lonelyCopy
Lonely Hearts from this page and paste it into your editor or
save it as a text file which you should be able to load
straightforwardly into your workspace.
To run Lonely
Hearts just type:
print lonely or (for short) pr
If you are feeling really lazy try:
10 [print lonely]
Some suggestions for when you are
bored . . .There are many ways in which you could test
or modify the Lonely Hearts system and, in doing so, gain practice
in understanding and developing procedure definitions. Don't feel restricted
or inhibited by the suggestions which follow:
1. Run each of the procedures
separately. E.g type someone
by itself or age. This will at very least
reinforce the point that Lonely Hearts is a set of tools occupying a workspace
rather than an indissoluble program.
2. Replace lonely
by a new superprocedure (perhaps called lonely2)
which ties the lower level procedures together in some different way. You don't
need to worry about removing or otherwise disabling the original lonely.
It will co-exist
quite happily with your new procedure. They are just different tools. Maybe
you could define the new procedure as a command so that the user need only type
lonely2 not print lonely2.
Change the content of the lists which the various pickrandoms
choose from. This is trivial and you won't learn much from it - but
it can be fun.
4. To provide some more v ariation in the form of the advertisements,
define a new sub-procedure
seeks - on the model of description
- and then modify lonely by changing the word "seeks
to seeks. (Why do you
need to do that?)
And for something completely different . . .
Investigate the possibilities of a different sub-language.
There are many similarly restricted uses of language which will provide you
with scope to practice the mechanics
of procedure definition. And you don't really need to stick to a single
sentence pattern. (Remember that print provides a <return>
at the end of a line it displays.)
Instead of Lonely Hearts
ads, for example, you could experiment with houses for sale advertisements,
or tombstone epitaphs or weather forecasts (plenty of opportunity to use pickrandom
there.). Take a look at some real examples of the data
you plan to model and attempt
to make some simple generalisations about the form of the texts before you get
down to writing out Logo procedures.
