CODE:

FUNCTION poissondist,fLambda,N
FOR i=1,N,1 DO BEGIN
a = FLTARR(N)
r = RANDOMU(SEED,1)
FOR j=1,N,1 DO BEGIN
x=poisson(j,fLambda)
if abs(x-r) lt 0.0001 THEN a[i]=j
ENDFOR
ENDFOR
RETURN,a
END
*****************************************

when i becomes equal to N you will get an error
trying to access a[i].
Also, your a[0] is equal to zero.

And, your function is
FUNCTION poissondist, fLambda, N
and you call it like:
x=poisson(j,fLambda)

Note that flambda is in the wrong position.
