The default OperandSize and AddressSize to use for each instruction is given by the D bit of the segment descriptor of the current code segment - D=0 makes both 16-bit, D=1 makes both 32-bit. Additionally, they can be overridden on a per-instruction basis with two new instruction prefixes that were introduced in the 80386:
In a binary search tree, a right rotation is the movement of a node, X, down to the right.This rotation assumes that X has a left child (or subtree). X's left child, R, becomes X's parent node and R's right child becomes X's new left child.
Another example may be an 8-bit register with the bit pattern 01010101 and the carry flag set; if we execute a rotate left through carry instruction, the result would be 10101011 with the carry flag cleared because the most significant bit (bit 7) was rotated into the carry while the carry was rotated into the least significant bit (bit 0).
Calculators that implement TI-BASIC have a built in editor for writing programs. While the considerably faster Z80 assembly language [2]: 120 is supported for the calculators, TI-BASIC's in-calculator editor and more user friendly syntax make it easier to use. TI-BASIC is interpreted.
In addition to the PIC18's four rotate instructions, the H08A has ARLC (identical to RLCF, but also sets the overflow flag if the sign bit changes) and ARRC, which is an arithmetic right shift, preserving the msbit of the source.
In addition, some constructs in standard ANSI C code may be optimized by a compiler to the "rotate" assembly language instruction on CPUs that have such an instruction. Most C compilers recognize the following idiom, and compile it to a single 32-bit rotate instruction. [1] [2]

Originally, calculator programming had to be done in the calculator's own command language, but as calculator hackers discovered ways to bypass the main interface of the calculators and write assembly language programs, calculator companies (particularly Texas Instruments) began to support native-mode programming on their calculator hardware ...
