Second Script, about column input and printing
  ==============================================

* First look at cases of column and free-format input, mixed,
  to see what works;

   data examp0;
      infile "testdat";
      input subject 2-3 gender $ Exam2 12-13 Hwgrade $ Exam1 8-9;
  run;

* So you can mix the variable formats as long as data is 
  exactly in the advertised columns, and the free-format
  columns exactly follow the last-mentioned ones with 
  designated column numbers;

 data examp1;
      infile "testdat";
      input  Exam2 12-13 Hwgrade $ Exam1 8-9 subject 2-3 gender $ ;
  run;
         proc print;
            title "examp0 output";
               run;

                    examp0 output   

Obs    Exam2    Hwgrade    Exam1    subject    gender

  3       86        B         90         4        F
  4       85        B         82        20        M
  5       94        A         94        25        F
  6       84        C         88        14        F

*----------------------------------------Printing----------;
1     libname myhom ".";
2             data tmp1;
3               set myhom.examp2;
4                                run;

* the next lines show how to get title;

5      proc print;
6        title "Example Print Title";
7                                     run;

* but the first (extra) column in the printout was "OBS" 
  which just numbers observations, and this column can be
  suppressed either, by using option "noobs", as follows;

8      proc print noobs;
9        title "Example Print Title";
10                                    run;

* OR by specifiying an ID (identifier) variable which will
automatically be made the first column. With ID specified, 
as follows, the option NOOBS has no effect whatever;

11     proc print noobs;
12       id HWgrade;
13       title "Example Print Title";
14                                    run;
