I need to concatenate few numeric values into one character variable.
One way to do is create char copies of the int variables, concatenate
them and then drop the char copies. Is there any other better way to
typecast and use the variables. I am creating a gene string for
implementing genetic algo. So, this stuff needs to be done in every
iteration; and number of iterations could be in 000s. Creating and
dropping again and again is something i would not prefer doing.

Can anyone help???

Are you talking about this?

data tt;
a=1;
b=2;
c=3;
abc=cats(a,b,c);
put abc=;

run;

Usually I define a variable length for any variable derived from cats,
scan, because SAS use $200 for the variable. Most time it is too big.
