We give upper bounds on the size of the gap between the constant term
and the next nonzero Fourier coefficient of an entire modular form of
given weight for inverted right perpendicular (0)(2). Numerical eviden
ce indicates that a sharper bound holds for the weights h equivalent t
o 2 (mod 4). We derive upper bounds for the minimum positive integer r
epresented by level-two even positive-definite quadratic forms. Our da
ta suggest that, for certain meromorphic modular forms and p = 2, 3, t
he p-order of the constant term is related to the base-p expansion of
the order of the pole at infinity.
