I'm trying to randomize values between .20 and .25. I'm not sure how
to manipulate that with:

ranuni(123)

thanks,

This gives you 100 random numbers in the desired range.

data RandomNums(drop=i);
do while(i<100);
RandomNumber=ranuni(123);
if RandomNumber>=0.2 and RandomNumber<=0.25 then
do;
output;
i+1;
end;
end;
run;

randomInRange = rangeBottom + (rangeTop-rangeBottom) * RANUNI(0);

Read help on RANUNI(seed) to understand how the seed argument is used.
RANUNI is one of a family of RAN* call routines for random number
generation (RNG). The other routines produce output that conform to
various distributions such as Normal or Poisson.

In your specific case:

x = 0.20 + 0.05 * ranuni(0);

Oops! Yes, of course! That's how it's done best.
Thanks, Richard
