Cleaning Messy Data in SAS

I have the following data stored in a character variable Payment:

87.69/88.20/150.50//183.60195.8987.00/88.35//195.28/47.40/99.2260.34//20.45//325.00/96.45295.00/96.54  Which function should I use to count the number of payment per line to calculate the totalexpense?('/'separate the payment)

data have;
   input payment : $80.;
   cards;
87.69/88.20/150.50//183.60
195.89
87.00/88.35//195.28/47.40/99.22
60.34//20.45//325.00/96.45
295.00/96.54
;

data want;
   set have;
   total_payment=0;
   i=1;
   tmp=input(scan(payment,i,"/"),best.);
   do while (^missing(tmp));
            total_payment+tmp;
            i=i+1;
            tmp=input(scan(payment,i,"/"),best.);
        end;
    N_payment=i-1;
    drop i tmp;
run;

183.60195.8987.00，多个小数点的数字是什么？

87.69/88.20/150.50//183.60
195.89
87.00/88.35//195.28/47.40/99.22
60.34//20.45//325.00/96.45
295.00/96.54

Which function should I use to count the number of payment per line and to calculate the total Payment?('/'separate the payment)

data _null_;
test="87.69/88.20/150.50//183.60195.8987.00/88.35//195.28/47.40/99.2260.34//20.45//325.00/96.45295.00/96.54";
num=count(a,'/')+1;
put num=;
run;

How to caculate the total of each line?
Do I need to do the calculation by two steps:
(1) Read each data separated by ‘/’；
(2) Transform the data into numeric type;

Or is there any function to do this take directly?
