Dear Statalisters,

I am writing a do file that uses -rndbin- to generate a second variable,
xb. As you all know -rndbin- runs as:

rndbin obs prob numb

However, the do file repeats that task X times and, in some cases, _n is
greater than obs. Hence, for examaple, the following error shows up:

obs must be between 32 and 582539
r(198);

Indeed, in one out of X runs of the loop, the local `observations' assumes
value of 19. The problem is that _n=32 in the dataset.

Thence,

rndbin 19 0.05 1

obs must be between 32 and 582539
r(198);

So, I would like to know if there is a way to solve this problem... say...
run -rndbin- in a way that the variable xb is not created.

Thank you again for your time and help.

Tiago
