The instructions to be described on this page have the formats, taken from the main illustration of instruction formats on the first page of this section, shown in this diagram:
As well, the 33-bit alternate instructions as illustrated in this diagram:
include memory-to-register operate instructions, which are also listed below.
And the 48-bit memory reference instructions, as illustrated in this diagram:
both the form that only uses one bit to indicate an index scaled to the operand size, and the form that uses a three-bit field, to allow the left shift to be applied to the index to be specified directly, are listed below as well.
The opcodes for these instructions are:

Most of these operations were defined on the page concerning 17-bit and 15-bit instructions.
Subsequent pages will give opcodes for additional instructions with these formats, for performing operations on data types other than two's complement binary integers and IEEE 754 (or similar, in the case of the Medium length) floating point.
