     The put_line above should be changed to

put(net_pay, AFT=>3,EXP=>0);
new_line;

because Float_IO (and therefore flt_io) doesn't have a put_line, only a
put.  (The new_line in the corrected code above will come from Text_IO.)

     Also, since you're not using dot notation for the packages, you
should add USE clauses to your three instantiations, like this:

package flt_io is new Float_Io(Float); use flt_io;
package int_io is new Integer_Io(Integer); use int_io;
package boolean_io is new enumeration_io(Boolean); use boolean_io;

     That should fix everything.  When you run the program and type the
number of dependents, don't forget that you're inputting a float.  E.g.,
type "3.0", not "3".  I hope this helps.
