Load a Partition (LOAD)Source:LOADObject:II23 31D Load parameters:Bits:12 0 = Load a full partition; P is not specified.1 = Load a partial overlay; P is specified.13 0 = Do not attempt a background attach; A is not specified.1 = Attempt a background attach; A is specified.14 Not used, always O.15 0 = System is providing error handling; E is not specified.1 = Program is providing error handling; E is specified.fJ Load parameters address: The address of data area that contains the loadparameters, or all zeros if the data area label is not specified. If the label isomitted the operator will be prompted to enter the load parameters fromthe keyboard.This instruction loads a partition according to the load parameters. The load parametersmay be entered from the keyboard or may be read from a data area. If theparameters are to be read from a data area, they must be stored in the followingformat:1. Partition number; 2 bytes in length. The partition number may contain: (a)the number (hex 0-7) in the first byte and blank (hex 40) in the second byte,(b) the 2-byte logical ID assigned to the partition in the resource allocationtable, or (c) two blanks (hex 40) if the current partition is to be reloaded.2. Device address; 4 bytes in length. The device address may contain: (a) the4-byte physical address of the device that contains the data set to load, or (b)the 2-byte logical device ID assigned to the device in the resource allocationtable, followed by two blanks (hex 40).3. Start address; 2 bytes of hex digits, used only for a partial overlay. Theaddress must be on a 256-byte boundary and must be greater than hex 100.182
