st: Simple Question - Use of rndbin |

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.
