Abstract: There is disclosed a method of converting a software program for a single processor to that for a multiprocessor. In the method, to prepare an execute form program for operating software running on a single memory space on the multiprocessor, a source file is allocated to each processor by an object file unit to prepare the execute form program for each processor. The execute form program is mounted on the memory space managed by each processor with an arrangement in which addresses are prevented from being duplicated among the processors.

Abstract: An improved measuring rule for measuring the pupillary distance between a person's eyes is provided wherein a disc is both rotatably and slidably supported on an index rule, the disc being similarly indexed. By positioning the disc over the pupil of an eye while the person is wearing a pair of lens-receiving frames, the disc provides measurement of the required lens blank size necessary for those frames simultaneously with the measurement of the pupillary distance. The disc also facilitates the measurement for a bifocal lens and also indicates any required vertical height adjustment caused by an optical abnormality.
