trying DM 8.23 compiler in DOSX model.

i only replaced bin\SCPPN.EXE and bin\SCPPND.EXE

i had

typedef enum boolean {false,true};

in a header.
it does not compile any more: "identifier expected"

not a big problem, just for information

- i mean bin\SCPPND.DLL

- sorry outpw, inpw are still 32 bit contrary to what compiler.htm says

Hi,
        I can generate this too, but only by using a conio.h to provide the
prototypes
for inp*/outp*:

====== CODE GENERATES inpw/outpw as 16 bit
#include <stdint.h>
// #include <dos.h>
#include <conio.h>

const baseAddress = 0x300;

int main (int argc, char * argv[])
{
  uint8_t  i8;
  uint16_t i16;
  uint32_t i32;

 // Generate 3 inputs
  i8  = inp (baseAddress);
  i16 = inpw(baseAddress);
  i32 = inpl(baseAddress);

 // generate 3 outputs
  outp (baseAddress, i8);
  outpw(baseAddress, i16);
  outpl(baseAddress, i32);

  return 0;
}
====== END of CODE GENERATES inpw/outpw as 16 bit

This variant below (the one I've used) works 100%, fully inline and
_inpw/_outpw are 16
bit with -mx.
The changes are the _ before the inp* and outp* and the use of dos.h rather than
conio.h :

====== CODE that works
#include <stdint.h>
#include <dos.h>
// #include <conio.h>

const baseAddress = 0x300;

int main (int argc, char * argv[])
{
  uint8_t  i8;
  uint16_t i16;
  uint32_t i32;

 // Generate 3 inputs
  i8  = _inp (baseAddress);
  i16 = _inpw(baseAddress);
  i32 = _inpl(baseAddress);

 // generate 3 outputs
  _outp (baseAddress, i8);
  _outpw(baseAddress, i16);
  _outpl(baseAddress, i32);

  return 0;
}
====== END of CODE that works

======== build lines ...
sc -mx -c -C ioTest.Cpp
Obj2Asm ioTest.Obj >Fixed.Dmp
========

The problem appears to be the conio.h on my system, The 'offending' conio.h on
my
system is :
    CONIO    H           8,091  03-17-01 12:15a CONIO.H
I've not checked the exact nature of the inp/outp prototypes in there, but I
assume
that they are substantially different to the updated ones in the dos.h that
appeared
with the 8.23 Beta.

Hi.
    I've just patched my DM up to the current code set cd81d, then cd823, and
the
incorrect code generation with conio.h remains.

 trying DM 8.23 compiler in DOSX model.

 i only replaced bin\SCPPN.EXE and bin\SCPPND.EXE

 i had

 typedef enum boolean {false,true};

 in a header.
 it does not compile any more: "identifier expected"



It should work, and it does for me (I also used 8.23, to be sure).  In C,
not in C++ (true and false are keywords in ISO-C++, they are the only
acceptable values for the bool type).  I wonder why this worked until
now, -Ab is default for some time (8.20, at least, if not sooner).  Probably
your header is included from a C++ file, and the compiler correctly
complains about misuse of a keyword instead of an (expected) identifier.

  Laurentiu
