This switch causes XPPN.SBR to adjust the value of the returned P (project) and PN (programmer number) values so that even though they appear in decimal as if they were octal. For example, if you are in PPN [100,377], it would normally return 64 and 255, since those are the decimal equivalents of the octal values 100 and 377. But with SBR=XPPNOCT, it will actually return the decimal values 100 and 377. Note however, that such numbers may not fit in a single byte, so the P and PN parameters should be at least 2 bytes long.
