SAS Forecasting mass

[VDD]

I have a hypothetical question.

How many humming birds does it take to lift an elephant? 

I know that everyone knows humming birds are the incorrect tool for the job, but in my scenario it is the only tool available in order to lift the elephant.  Besides the string that will be used to attach the humming birds to the elephant.

How would I go about writing in SAS a process where I could change the weight of the elephant and predetermine the number of humming for the job? 

elephant_weight = 100

humming_bird_lift_ability = ?

other_weight = ?

Thanks for any interaction with this scenario.

BTW the answer is 1 really smart humming bird that can indicate humming birds are the incorrect tool for the job.

%let elephant_weight = 1000;
%let birds_wgt_capacity = 5;
%let num_birds_needed = %sysfunc(floor(%sysevalf(&elephant_weight/&birds_wgt_capacity)));

data have;
sentence = "With an elephant that weights &elephant_weight. 
     and birds able to carry &birds_wgt_capacity., 
     then you need &num_birds_needed birds.";
run;

proc print data=have;
run;
