One idea: build the difference:

3.88-3.76=??

The random functions return numbers between 0 and 1 as far as I remember -
this ??-range you have to distribute over the 0-1 range and add the lower
limit:

data test;
  l0=3.76;
  l1=3.88;
  d=l1-l0;
  do i=1 to 100;
    x=d*ranuni(5)+l0;
    put x=;
  end;
run;
