SASM180 Advanced Macro
Assembler
 | SASM is FAST! On
today's systems, SASM will assemble most files in one or two seconds. Uses state of the
art high speed symbol management routines. |
| Supports multiple
processors: Intel 8080 and 8085, Zilog Z80, Z180, Z181, Z182, Z189, Z185, and Z195,
Hitachi HD64180, HD647180X and National Semiconductor NSC800, and all families using any
of these instruction sets. The Toshiba T6A84 is supported and now includes unsupported Z80
opcode emulation as is the T6B31. |
| Automatically
supports the Z180 MMU or hardware bank switching. Allows jumps and calls into segments
that aren't mapped into the logical address space. These may be viewed as "long"
jumps or calls. The linker SLINK automatically handles and provides the runtime mapping.
SASM is the only package that is truly automatic. No programming effort is required and no
registers are affected. |
| Generates full
source-level debugging information for each file including the source name, include files,
line numbers, public symbols, and local symbols. |
| Assembler evaluates
all expressions as 32-bit expressions (16-bit compatibility mode also supported).
|
| Can include binary
images or files into a program (e.g. FPGA logic, bitmapped display data, etc.).
|
| Supports unlimited
memory for unlimited labels and macro sizes. |
| T-State display and
accumulation supported for the Z180 processor family. |
| Supports many
directives that are compatible with those used by other assemblers.
|
| Includes full macro
support with parameter substitution and conditional assembly including string comparisons
without an external preprocessor. |
| Define symbols from a
dialog box to any valid assembler numeric constant. Defined symbols have a life span from
their definition to the end of SASM's execution. |
| Uses a multi-pass
design, which handles multiple forward references. Some source codes may be assembled in
one pass. All other source codes designed for two-pass assemblers will assemble in at most
two passes. A command line option may be used to force a two-pass assembly.
|
| Optimization may be
turned on to include files only on pass one of assembly. |
| Supports 256 named
code segments up to 1MB in size each per module. |
| Accepts expressions
with commonly used assembler operators and C language operator equivalents (where
applicable). |
| All expressions
regardless of complexity or operators used can be evaluated at link time.
|
| Can access the start,
end and size of segments and physical addresses assigned to segments and symbols at link
time. |
| Printer control
strings can be injected into the listing file at any time.
