Based on Don's article, which, by the way was dated 27 Nov 87, I called
Microsoft and was told the same thing.  The disk arrived last week.  It
turns out that it was written by company called Glockenspiel in Dublin,
Ireland.  By the way, the 8 files that make up the package are now
available on Compuserve in DL3 of the MSSYS forum.  Check with the MSSYS
sysop for exact file names.  Microsoft says to feel free to make copies
and pass them around.

As a baseline, I wrote a very simple Turbo Pascal program and ran it
through the translator.  Here is the Turbo Pascal source:
Program Main;
     WriteLn('Hello world!');
Here is the output of the translator:
#include        <stdio.h>
#include        <string.h>
#include        <turbo.h>
int T2C_paramcount;
char **T2C_paramstr;
unsigned char huge * T2C_mem_array = 0;
unsigned int huge * T2C_memw_array = 0;
main (argc,argv)
int argc;
char *argv[];
T2C_paramcount = argc - 1;
T2C_paramstr = argv;
T2CF_write(&T2C_CON,"%s\n",1,"Hello world!");
The resulting C code isn't very pretty, but it compiled and ran correctly
using the MSC 5.0 compiler.  Incidentally, the translator requires that
program be compiled using the large model and linked to a special library
that is supplied as part of the translator package.  The startling thing
to me was that the size of the executable (.exe) file for this program was
70361 bytes!  A comparable program written in "native" C and and compiled
under MSC 5.0 produces an executable file 9309 bytes in length using the
large model and 7075 bytes in length using the small model.  The translator
appears to call in a lot of excess baggage from the library ....
I tried the translator on two larger Turbo Pascal programs that I had
handy, and it didn't work on either one.  I must admit that I wasn't
sufficiently motivated to try very hard to make it work ....
The prospect of maintaining or modifying the kind of code the translator
produces does not particularly appeal to me.
