As for me I've found two places where may be errors:

#1 >> with Float_Text_IO;

Are you sure that this package exists? The standard package is called
TEXT_IO.FLOAT_IO.

Or if the IO package is of your own, then check whether its has been compiled
_before_ you're trying to compile your sample.

#2 >>  A, B : FLOAT := 0.0;

This may an error too, the thing is that decimal IS NOT a sign of a FLOAT-type
constant, it is a sign of a FIXED-type constant. The FLOAT-type constant
should be written so 12.34E56, it IS to have a power_of_ten postfix. This
detail is mentioned in the LRM ( I've got the Ada83 one only ).
