Hi All, Currently subtract for boolean arrays is defined in
/**begin repeat * Arithmetic operators * * # OP = ||, ^, &&# * #kind = add, subtract, multiply# */ static void [EMAIL PROTECTED]@(char **args, intp *dimensions, intp *steps, void *func) { register intp i; intp is1=steps[0],is2=steps[1],os=steps[2], n=dimensions[0]; char *i1=args[0], *i2=args[1], *op=args[2]; for(i=0; i<n; i++, i1+=is1, i2+=is2, op+=os) { *((Bool *)op)=*((Bool *)i1) @OP@ *((Bool *)i2); } } /**end repeat**/ Note that this might yield unexpected results if the boolean value is not 0 or 1, which is possible using views. Note also that bitwise_xor converts the boolean to 0 or 1 before using ^. I think subtract should work the same way, but that would change current behavior. So... do I make the change and call it a bug fix or leave it as it is? Chuck
