                        Helpful Hints

I have set up the accounts so that you have access to common
files.   Included  are all the ASSEMBLER programs  found  in
these  classnotes, as well as all the programs you need  for
your labs.  These are available as file mode B.


Some of you may get an error message from the editor to  the
effect  that FILEMODE Bis read only.  This will  occur  when
you try to save a program.


This occurs because there is an extra disk connected to your
account.  It contains all the programs we did in class  plus
a few other items.


You can get around this by typing
     FILE blah ASSEMBLE A

where  "blah"  is  the name that you want to  use  for  your
program.  Note that the "A" filemode is explicitly stated.

Generally, if you avoid names beginning with "$"  you  won't
have this problem.  E.G. call your programs, HWKnn or ASSnn.

3.   You  can type "FILELIST * * B" to see the programs  for
     you to look at.

4.   COPY blah ASSEMBLE B = = A
      will make a copy of one of your supplied programs
     on your own minidisk.


               How to turn in your assignments

In  order  to  check your programs, I have to  do  the  same
things  you  do.   Inspect the listing to  find  the  memory
locations  of  the  "BR  14" and the "DC's"  containing  the
variables containing the results.

Thus,  I  need  an  electronic version of your  program.   A
printed listing does me absolutely no good.

The  best way to get graded would be to come by the lab  and
let  me grade you "while-u-wait."  YOu get a bonus for doing
this.   However,  if  this  is not  feasible  for  you,  the
following  procedure will allow you to submit an  electronic
version.

The  following procedure will cause the file to be  sent  to
the appropriate account, it is a form of electronic mail.

1.   To submit your computer assignments, simply

          a.   type "turn_in"
          b.   The computer will prompt,
                "Enter the name of the file you want to turn
          in.
                 Type the name, e.g. "blah"
                Do not type the extension.  The machine will
          figure out that you need to send the ASSEMBLE file
          which is the only thing I need.

          c.   The computer will say
                blah  ASSEMBLE sent to MCS080 at  ECNIBM  at
          date (or something similar)

               where blah is whatever you call your program
