range

    Location in memory to be searched. A location can be represented
    by any valid SDA expression. To search a range of locations, use
    the following syntax:

    m:n  Range of locations to be searched, from m to n
    m;n  Range of locations to be searched, starting at m and
         continuing for n bytes

    You must use either an equals sign or a blank to separate range
    from expression or string.

 expression

    Value for which SDA is to search. SDA evaluates the expression
    and searches the specified range of memory for the resulting
    value. For a description of SDA expressions, type HELP
    EXPRESSIONS.

 string

    Character sequence for which SDA is to search. If all characters
    in the sequence are printable characters, the string is enclosed
    in quotes, for example,
    "My_String". If the character sequence contains nonprintable
    characters, it must be specified as a comma-separated list
    composed of quoted strings and hexadecimal numbers; for example,
    ("My_String",0C00,"More") would specify a search for "My_
    String<NUL><FF>More". Each hexadecimal number can be no more
    than 8 digits (4 bytes) in length. Nonprintable sequences of more
    than 4 bytes must be split into multiple hexadecimal numbers.
    The maximum length of a search string is 127 bytes. Note that the
    quote character itself cannot be included in a quoted string and
    must be specified as a hexadecimal number.
