--EXPR--
An expression is a combination of numeric values, symbols, operators, and
parentheses used to specify address, data, status, executed address, or any
other value used in the emulation commands.
The function of an expression (--EXPR--) is to let you define the address,
data, status, or executed address expression that fits your needs. You can
combine multiple values to define the expression.
Certain emulation commands will allow the option of <+EXPR> after pressing
a thru softkey. This allows you to enter a range without retyping the original
base address or symbol. For example, you could specify the address range
disp_buf thru di 25
as
disp_buf thru +25
The parameters are as follows:
DON’T CARE
NUMBER
You can include "don’t care numbers" in expressions. These are indicated by
a number containing an "x." These numbers may be defined as binary, octal,
decimal, or hexadecimal. For example: 1fxxh, 17x7o, and 011xxx10b are
valid.
Note that "Don’t care numbers" are not valid for all commands.
--NORMAL--
This appears as a softkey label to enable you to return to the --EXPR-- key.
The --NORMAL-- label can be accessed whenever defining an expression, but
