VMS Help  —  EXAMINE
    Displays the contents of virtual memory.

    Requires user-mode read (R)  access to the virtual memory
    location whose contents you want to examine.

    Format

      EXAMINE  location[:location]

1  –  Parameter 

 location[:location]

    Specifies a virtual address or a range of virtual addresses
    (where the second address is larger than the first) whose
    contents you want to examine. If you specify a range of
    addresses, separate the beginning and ending addresses with a
    colon (:).

    A location can be any valid arithmetic expression containing
    arithmetic or logical operators or previously assigned symbols.
    Radix qualifiers determine the radix in which the address is
    interpreted; hexadecimal is the initial default radix. Symbol
    names are always interpreted in the radix in which they were
    defined. The radix operators %X, %D, or %O can precede the
    location. A hexadecimal value must begin with a number (or be
    preceded by %X).

    The DEPOSIT and EXAMINE commands maintain a pointer to the
    current memory location. The EXAMINE command sets this pointer
    to the last location examined when you specify an EXAMINE
    command. You can refer to this location using the period (.)
    in a subsequent EXAMINE command or DEPOSIT command.

2  –  Qualifiers

2.1    /ASCII 

    Displays the data at the specified location in ASCII format.

    Binary values that do not have ASCII equivalents are displayed as
    periods (.).

    When you specify the /ASCII qualifier, or when ASCII mode is the
    default, hexadecimal is used as the default radix for numeric
    literals that are specified on the command line.

2.2    /BYTE 

    Displays data at the specified location, one byte at a time.

2.3    /DECIMAL 

    Displays the contents of the specified location in decimal
    format.

2.4    /HEXADECIMAL 

    Displays the contents of the specified location in hexadecimal
    format.

2.5    /LONGWORD 

    Displays data at the specified location, one longword at a time.

2.6    /OCTAL 

    Displays the contents of the specified location in octal format.

2.7    /WORD 

    Displays data at the specified location, one word at a time.

3  –  Examples 

    1.$ RUN   MYPROG
 <Ctrl/Y>

      $ EXAMINE   2678
      0002678:  1F4C5026
      $ CONTINUE

      In this example, the RUN command begins execution of the image
      MYPROG.EXE. While MYPROG is running, pressing Ctrl/Y interrupts
      its execution, and the EXAMINE command displays the contents of
      virtual memory location 2678 (hexadecimal).

    2.$ BASE = %X1C00
      $ READBUF = BASE + %X50
      $ ENDBUF = BASE + %XA0
      $ RUN   TEST
 <Ctrl/Y>

      $ EXAMINE/ASCII READBUF:ENDBUF
      00001C50:  BEGINNING OF FILE MAPPED TO GLOBAL SECTION
         .
         .
         .

      In this example, before executing the program TEST.EXE,
      symbolic names are defined for the program's base address and
      for labels READBUF and ENDBUF; all are expressed in hexadecimal
      format using the radix operator %X. READBUF and ENDBUF define
      offsets from the program base.

      While the program is executing, pressing Ctrl/Y interrupts
      it, and the EXAMINE command displays in ASCII format all data
      between the specified memory locations.
