HOW TO RUN THE PROBLEMS IN AMBPROBS IN THE AMB INTERPRETER

1. Start up DrScheme.

2. In DrScheme, open the ambprobs file.

3. In DrScheme, open the ambmicro.scm file.  This will create a second
DrScheme window with ambmicro.scm in it.  You need both screens.

4. Execute the ambmicro.scm that was just loaded.

5. In the interpreter window, execute the command (micro-r-e-p).
This starts ambmicro.

6. Go to the other DrScheme screen capture one or more procedure definitions
using the copy command on DrScheme's Edit menu.

7. Move the cursor to the right of the waiting ambmicro> prompt in the
other window and deposit the definitions with the paste command on that
window's Edit menu.  Leave a little space between the prompt and the
cursor; if they are too close together, DrScheme won't take the input.

8. Press the return key after the paste operation to cause ambmicro to
read it.  Be patient, the interpreter is slow and may take several seconds
to read a long sequence of definitions.

9.  Now you can type the command that runs the desired problem such
as (bank-jobs) or (parse '(time flies like arrows)).

Note: You can also run the problems in ambmicrotracer, which displays a
trace of what is happening.  Just open "ambmicrotracer" in place of
"ambmicro.scm" and skip step 5 (ambmicro starts up by itself).  It
produces a lot of output and is very slow.
