- Modula-2/68
- _____________
-
- Modula-2/68 is a language system producing machine code for the Motorola
- MC68000 family of microprocessors. The product consists of a Modula-2
- compiler, linker, library modules, and documentation. This product was built
- in 1985 from Smiler2 a Modula-2 compiler and linker developed at the Institut
- fur Informatik of the Eidgenossische Technische Hochschule in Zurich,
- Switzerland.
-
-
- This modern programming language is designed for building complex software
- systems. It combines low-level access to machine resources with features to
- support modern design concepts for the specification of global information and
- program modularity.
-
- Language Features Include:
-
- o Pascal Like Well Structured Programs.
-
- o Abstract Data Types.
-
- o Definition and Implementation Modules.
-
- o Separate Compilation of Modules.
-
- o Optional Run-Time Checks.
-
- o Module Libraries can be shared.
-
- o Access to Low-Level Hardware Dependent Facilities.
-
- o IMPORT and EXPORT statements for specifying global procedures, variables,
- and types.
-
- o INTEGER, LONGINTEGER, CARDINAL, LONGCARDINAL, REAL, LONGREAL, BOOLEAN, CHAR,
- BYTE, and BITSET data types.
-
- o ENUMERATION, SUBRANGE, ARRAY, SET, RECORD, and PROCEDURE types for building
- abstract data structures.
-
- o Arithmetic and Logical operators.
-
- o WHILE, FOR, REPEAT, and LOOP statements for iterative execution of
- statements.
-
- o IF, ELSEIF, and CASE statements for conditional execution of statements.
-
- o Fast compilation.
-
- o Compact, high-performance object code.
-
- o Compile-time consistency checking of date and time version skews.
-
- o Programs can call external routines written in other high level languages
- in addition to assembly language routines.
-
- o Optional run-time checking for array bounds, subrange assignment, variant
- record tags, case selectors, and function without return.
-
- o Uses the IEEE floating point format and operations for REAL data types.
-
- o Unix style user defined directory search lists for locating symbol and
- object libraries.
-
- o Program access to Unix shell command line argument information via the ARGC
- and ARGV global values.
-
- o Reformats a Modula-2 program according to a standard set of pretty-printing
- rules.
-
- o Makes a cross reference list and program listing with numbered lines.
-
- o Data Storage Types & Sizes:
-
- ADDRESS 4 bytes
- BITSET 4 bytes
- BOOLEAN 1 byte
- BYTE 1 byte
- CARDINAL 4 bytes
- CHAR 1 byte
- INTEGER 4 bytes
- LONGCARDINAL 4 bytes
- LONGINTEGER 4 bytes
- LONGREAL 4 bytes
- POINTER 4 bytes
- PROCEDURE 4 bytes
- REAL 4 bytes
- SCALAR1,2 or 4 bytes
- SET 1,2 or 4 bytes
- SHORTWORD 2 bytes
- SUBRANGE 4 bytes
- WORD 4 bytes
-
-
- Two versions of the procedure libraries are available. One for host system
- execution, the other for cross development using a different version of the
- SYSTEMX run time support Module.

- _________________
-
- Modula-2/68 is more than a standard compiler for use on Unix systems and
- workstations. It is also a cross-development tool producing code for use on
- target MC68000 family machines using other operating systems, or no operating
- system at all. Cross development is done using compiler and linker options,
- and a version of the Modula-2 libraries specially prepared for use on special
- target systems.
-
- o Compiler option to produce code that does not depend on a host operating
- system.
-
- o Linker option for standard Motorola S-record output.
-
- o Linker option for specifying the absolute location of data and code.
-
- o Linker option for specifying base addresses by module name for code and
- data.
-
- o Symbol table information for linking to existing ROMS and symbolic
- debugging.
-
- o Support in Module SYSTEM for:
- ASH, BIT, CODE, REGISTER, SETREG, NEWPROCESS, TRANSFER, IOTRANSFER, and
- SYSCALL.
-
- The ASH, BIT, CODE, REGISTER, and SETREG procedures allow for the insertion of
- machine code sequences that have full access to stack and frame variables.
-

-
- The documentation contains thorough descriptions of compiler, linker, and
- cross development options, with over 250 pages of detailed descriptions of
- library procedures with many examples.
