Jon,
VFP (and earlier FP versions) will initialize a new array if the second array (your laarray2) doesn't exist. It treats a single-element array as if it were just initialized, but if the array exists and is larger than a single element VFP assumes you want to overwrite it element by element with the first array. Then you get into the problems you saw with subscripts. The solutions are to a) release the array variable, b) redimension it as a single element array or c) redimension it with the same size/structure as the first array.
