fscanf equivalent? (for ease of model loading.)

i really need to know if there's a command equivalent to fscanf() from c, in blitzmax. if there isn't, then how would i achieve a similar effect to it? if you're curious, it's for loading .obj files in blitzmax + opengl.

fscanf is a stream function so:
