Version 6.0 contains a new global optimizer, automatic register variable support, in-line function support, optimized libraries, and upgrades to the compiler. The Lattice C Compiler v6.0 allows program modules compiled under different memory models to be linked into a single program.

The Lattice v6.0 now includes LASM, a full-featured macro assembler with support for 386 systems. LASM is compatible with MASM, and its output is compatible with CodePRobe so assembly language programs can also be debugged at source level. Utilities now bundled with the compiler are an overlay linker, a MAKE facility, BIND Utility, and several UNIX-like tools including EXTRACT and BUILD, DIFF, GREP, SPLAT, TOUCH, and WC. Programmer's tools in the compiler package include the CodePRobe source level debugger, an integrated editor, object module disassembler, object module librarian, and an automatic installation program.

In addition to the OS/2 API and special graphics libraries in the previous version, Lattice adds its Curses screen management library, communications library, the dBC III library of database functions, and a protected mode OS/2 library.

The new list price of $250 includes unlimited free technical support through Lattice's telephone hotline, bulletin board, MIX network, or written correspondence. Lattice provides an unconditional, 30-day money-back guarantee with each product.

Dr. MD will not allow you to overwrite allocated or automatic variables. When Dr. MD finds a problem it reports the source file and the line number where the problem was found as well as where the space was allocated. No heap walking is needed.

Dr. MD comes as source and you compile it with your compiler to fit your environment. The vendor claims it should work with any ANSII standard compiler, and has worked successfully in MS-DOS and UNIX System V environments. Dr. MD supports all the string library functions as well as memset, memcpy, and limited support of sprintf.

Each of the NDP-486 compilers include a "scheduler/code generator" that aligns code and data on paragraph boundaries, detects and minimizes prefetch buffer starving, uses new code sequences that run faster on the 80486 than the 80386, and incorporates a new strategy for driving the Weitek 4167 high speed coprocessor. They also provide a library of 70 device-independent graphics, keyboard, and sound routines.

C, NDP Fortran, and Pascal-486 generate globally optimized, 32-bit native code that runs in protected mode under UNIX 386 System V v3.0, SCO XENIX 386 v2.3, and Phar Lap extended DOS. The compilers support the 486's built-in FPU and the Weitek 4167 numeric coprocessor.

NDP C-486 is a two-dialect compiler that passes 100 percent of the Plum Hall validation suite for UNIX System V C and 95 percent of the tests for the new ANSI C standard. It includes an inline assembly language interface that simplifies the writing of embedded code by allowing the programmer to specify register values and generate interrupts.

The MS-DOS, UNIX, and XENIX versions of NDP C-486, NDP Fortran-486, and NDP Pascal-486 retail at $1195 each. The C + + preprocessor lists at $495. All of the compilers include one year of free updates.
