valid when "C" appears on the status line, which indicates a valid expression has
been defined.
<NUMBER>
This can be an integer in any base (binary, octal, decimal, or hexadecimal), or can
be a string of characters enclosed with quotation marks.
<OP>
This represents an algebraic or logical operand and may be any of the following (in
order of precedence):
--SYMB--
This allows you to define symbolic information for an address, range of addresses,
or a file. See the --SYMB-- syntax pages and the Symbolic Retrieval Utilities
User's Guide for more information on symbols.
end
This displays the last location where the symbol information may be located. For
example, if a particular symbol is associated with a range of addresses, end will
represent the last address in that range.
start
This displays first memory location where the symbol you specify may be located.
For example, if a particular symbol is associated with a range of addresses, start
will represent the first address in that range.
<UNARY>
This defines either the algebraic negation (minus) sign (-) or the logical negation
(NOT) sign (~).
( )
Parentheses may be used in expressions to enclose numbers. For every opening
parenthesis, a closing parenthesis must exist.
Note that when "C" appears on the right side of the status line, a valid expression
exists. The --NORMAL-- key can be accessed at any time, but is only valid when
"C" is on the command line.
Note that when a thru softkey has been entered, a <+ EXPR> prompt appears.
This saves you from tedious repeated entry of long symbols and expressions. For
example:
