Generate the solutions using CLP solver in SAS/OR:
<lang sas>/* call OPTMODEL procedure in SAS/OR */
proc optmodel;
/* declare set and names of coins */
set COINS = {1,5,10,25};
str name {COINS} = ['penny','nickel','dime','quarter'];
/* declare variables and constraint */
var NumCoins {COINS} >= 0 integer;
con Dollar:
sum {i in COINS} i * NumCoins[i] = 100;
/* call CLP solver */
solve with CLP / findallsolns;
/* write solutions to SAS data set */
create data sols(drop=s) from [s]=(1.._NSOL_) {i in COINS} <col(name[i])=NumCoins[i].sol[s]>;
quit;
/* print all solutions */
proc print data=sols;
run;</lang>
