-

- 7 Nov 1983

-
-
- INTRO
-
- This assembler was written to provide a convenient means for assembly
- language functions to be linked into a BDS C program. The input file may
- contain global symbol definitions and up to 64 functions. One level of
- file 'include' is provided. The assembler generates a .CRL output file
- ready for linkage with CLINK.
-
-
-
- INVOCATION
-
- The command line format is:
-
- A>ACRL <source file>[.<extension>] [-o] [-p] [-v]
-
- If no extension is specified, ".CSM" is appended to the source file
- name. The optional switches are:
-
- -o do NOT generate an output file
- -p print a listing on the console
- -v list every byte generated (verbose)
-
- The assembly may be aborted from the console by typing ^C.
-
-
-
- SOURCE FILE FORMAT
-
- ACRL basically supports a subset of the standard Intel assembly
- language. The only extension is the function definition:
-
- <name> FUNCTION <func1>, <func2> ...
- .
- .
- .
- FEND
-
- <name> is the function name and must be 8 characters or less.
- Following the FUNCTION keyword is an optional list of other functions
- referenced, separated by commas.
-
-
-
-
- ACRL PSEUDO OPS
-
- INCLUDE Include filenames must be enclosed in single quotes.
- Nesting is not allowed.
-
- EQU Symbols defined outside of any function are known to
- all functions. Symbols defined within a function are
- local and may have the same names as local symbols in
- other functions.
-
- SET A local SET directive will refer to a previously defined
- global. If not previously defined, it is local.
-
- DB Takes a list of 8 bit expressions. Strings must be
- enclosed in single quotes.
-
- DW Takes a list of 16 bit expressions, any of which may be
- relocatable.
-
- DS Only one expression allowed. Storage will be filled
- with zeros.
-
- END As usual.
-
-
-
-
- EXPRESSIONS
-
- The following operators are supported (in order of precedence):
-
- - NOT HIGH LOW () (unary)
- * / MOD SHL SHR
- + -
- AND
- OR XOR
-
- Within a function, the dollar sign ($) has the value of the
- location counter. The standard relocation rules apply.
-
-
-
-
- EXAMPLES
-
- The file TEST1.CSM contains sample usages of all operators and
- pseudo ops. TEST2.CSM contains every 8080 instruction (in opcode
- order). All the possible errors are generated in TEST3.CSM.
