C.3 Operators

This section lists the VAX MACRO unary, binary, and macro string operators.

C.3.1 Unary Operators

Table C-3 summarizes the VAX MACRO unary operators.

Table C-3 Summary of Unary Operators
Unary Operator Operator Name Example Effect
+ Plus sign +A Results in the positive value of A (default)
- Minus sign -A Results in the negative (two's complement) value of A
^B Binary ^B11000111 Specifies that 11000111 is a binary number
^D Decimal ^D127 Specifies that 127 is a decimal number
^O Octal ^034 Specifies that 34 is an octal number
^X Hexadecimal ^XFCF9 Specifies that FCF9 is a hexadecimal number
^A ASCII ^A/ABC/ Produces an ASCII string; the characters between the matching delimiters are converted to ASCII representation
^M Register mask ^M<R3,R4,R5> Specifies the registers R3, R4, and R5 in the register mask
^F Floating point ^F3.0 Specifies that 3.0 is a floating-point number
^C Complement ^C24 Produces the one's complement value of 24 (decimal)

C.3.2 Binary Operators

Table C-4 summarizes the VAX MACRO binary operators.

Table C-4 Summary of Binary Operators
Binary Operator Operator Name Example Operation
+ Plus sign A+B Addition
- Minus sign A-B Subtraction
* Asterisk A*B Multiplication
/ Slash A/B Division
@ At sign A@B Arithmetic Shift
& Ampersand A&B Logical AND
! Exclamation point A!B Logical inclusive OR
\ Backslash A\B Logical exclusive OR

C.3.3 Macro String Operators

Table C-5 summarizes the macro string operators. These operators can be used only in macros.

Table C-5 Macro String Operators
Format Function
%LENGTH(string) Returns the length of the string
%LOCATE(string1,string2[,symbol]) Locates the substring string1 within string2 starting the search at the character position specified by symbol
%EXTRACT(symbol1,symbol2,string) Extracts a substring from string that begins at character position specified by symbol1 and has a length specified by symbol2

C.4 Addressing Modes

Table C-6 summarizes the VAX MACRO addressing modes.

Table C-6 Summary of Addressing Modes
Type Addressing Mode Format Hex Value Description Can Be Indexed?
General register Register Rn 5 Register contains the operand. No
  Register deferred (Rn) 6 Register contains the address of the operand. Yes
  Autoincrement (Rn)+ 8 Register contains the address of the operand; the processor increments the register contents by the size of the operand data type. Yes
  Autoincrement deferred @(Rn)+ 9 Register contains the address of the operand address; the processor increments the register contents by 4. Yes
  Autodecrement -(Rn) 7 The processor decrements the register contents by the size of the operand data type; the register then contains the address of the operand. Yes
  Displacement dis(Rn)
B^dis(Rn)
W^dis(Rn)
L^dis(Rn)
A
C
E 		The sum of the contents of the register and the displacement is the address of the operand; B^, W^, and L^, respectively, indicate byte, word, and longword displacement. Yes
  Displacement deferred @dis(Rn)
@B^dis(Rn)
@W^dis(Rn)
@L^dis(Rn)
B
D
F 		The sum of the contents of the register and the displacement is the address of the operand address; B^, W^, and L^, respectively, indicate, byte, word, and longword displacement. Yes
  Literal #literal
S^#literal
0-3 		The literal specified is the operand; the literal is stored as a short literal. No
Program
Counter 		Relative address
B^address
W^address
L^address
A
C
E 		The address specified is the address of the operand; the address is stored as a displacement from the PC; B^, W^, and L^, respectively, indicate byte, word, and longword displacement. Yes
  Relative
deferred 		@address
@B^address
@W^address
@L^address
B
D
F 		The address specified is the address of the operand address; the address specified is stored as a displacement from the PC; B^, W^, and L^ indicate byte, word, and longword displacement, respectively. Yes
  Absolute @#address 9 The address specified is the address of the operand; the address specified is stored as an absolute virtual address, not as a displacement. Yes
  Immediate #literal
I^#literal
8 		The literal specified is the operand; the literal is stored as a byte, word, longword, or quadword. No
  General G^address --- The address specified is the address of the operand; if the address is defined as relocatable, the linker stores the address as a displacement from the PC; if the address is defined as an absolute virtual address, the linker stores the address as an absolute value. Yes
Index Index base-mode[Rx] 4 The base-mode specifies the base address, and the register specifies the index; the sum of the base address and the product of the contents of Rx and the size of the operand data type is the address of the operand; base mode can be any addressing mode except register, immediate, literal, index, or branch. No
Branch Branch address --- The address specified is the operand; this address is stored as a displacement from the PC; branch mode can only be used with the branch instructions. No
Key:
Rn ---Any general register R0 to R12. Note that the AP, FP, or SP register can be used in place of Rn.
Rx ---Any general register R0 to R12. Note that the AP, FP, or SP register can be used in place of Rx. Rx cannot be the same as the Rn specified in the base-mode for certain base modes (see Section 5.3 ).
dis ---An expression specifying a displacement.
address ---An expression specifying an address.
literal ---An expression, an integer constant, or a floating-point constant.

Appendix D
Permanent Symbol Table Defined for Use with VAX MACRO

The permanent symbol table (PST) contains the symbols that VAX MACRO automatically recognizes. These symbols consist of both opcodes and assembler directives. Table D-1, Table D-2, and Table D-3 present the opcodes (instruction set) in alphabetical and numerical order. Section C.1 (in Appendix C) presents the assembler directives.

See Chapter 9 and Chapter 10 for detailed descriptions of the instruction set.
