Defines
The Defines field is equivalent to placing <symbol> EQU <value> in your assembly source
code. It is useful for conditionally built code. Each defined symbol must have a corre-
sponding value (<name>=<value>). Multiple symbols can be defined and must be sepa-
rated by commas.
Generate Assembly Listing Files (.lst)
When selected, the Generate Assembly Listing Files (.lst) checkbox tells the assembler
to create an assembly listing file for each assembly source code module. This file displays
the assembly code and directives, as well as the hexadecimal addresses and op codes of
the generated machine code. The assembly listing files are saved in the directory specified
by the Intermediate
Files Directory field in the General page (see the Intermediate Files
Directory section on page 71). By default, this checkbox is selected.
Expand Macros
When selected, the Expand Macros checkbox tells the assembler to expand macros in the
assembly listing file.
Page Width
When the assembler generates the listing file, the Page Width field sets the maximum
number of characters on a line. The default is 80; the maximum width is 132.
Page Length
When the assembler generates the listing file, the Page Length field sets the maximum
number of lines between page breaks. The default is 56.
Jump Optimization
When selected, the Jump Optimization checkbox allows the assembler to replace relative
jump instructions (JR and DJNZ) with absolute jump instructions when the target label is
either
•
outside of the +127 to –128 range
For example, when the target is out of range, the assembler changes
DJNZ r0, lab
to
DJNZ r0, lab1

lab1:JP lab
