## 9.45 Version 2.0 Alpha November 5, 1997

- A new platform is now supported. exw.exe will run Euphoria programs using the WIN32 (Windows 32-bit) operating system. ex.exe will run programs using DOS32 (extended DOS). See platform.doc for further details.
- The following library routines have been introduced.
  - For both DOS32 and WIN32:
    - `platform()` - find out which platform you are executing on. (The PLATFORM constant is available in Euphoria 2.2 and later).
    - `routine_id()` - get a small integer id number for a Euphoria procedure or function.
    - `call_proc()` - call a Euphoria procedure by using its id.
    - `call_func()` - call a Euphoria function by using its id.
    - `custom_sort()` - sort a sequence using a compare function that you specify.
    - `poke4()` - store a number into 4 bytes of memory. poke4(address, value) is at least 10x faster than: poke(address, int_to_bytes(value)). poke4() also works with sequences of values."
    - `peek4s()` - read 4 bytes of memory as a signed integer (works on sequences too).
    - `peek4u()` - read 4 bytes of memory as an unsigned integer (works on sequences too). peek4u(address) is 10x faster than: bytes_to_int(peek({address, 4})).
    - `allocate_string()` - allocate and store a 0-terminated string in memory.
  - For WIN32 only:
    - `open_dll()` - open a Windows .dll file.
    - `define_c_proc()` - define a C routine that will be called from Euphoria (no value returned).
    - `define_c_func()` -define a C routine that will be called from Euphoria (a value will be returned).
    - `call_c_proc()` - call a C routine from Euphoria (no value is returned).
    - `call_c_func()` - call a C routine from Euphoria (a value is returned).
    - `call_back()` - get a call-back address, so Windows can call your Euphoria routine when the user interacts with your window."
    - `message_box()` - display a simple Yes/No/Cancel window.
- New Demo programs:
- csort.ex
- email.exw
- window.exw
- winwire.exw
- dsearch.exw
- New include files:
  - `safe.e` - debug version of machine.e"
  - `misc.e` - miscellaneous
  - `dll.e` - dll access
  - `msgbox.e` - Windows message box
- The following additional improvements have been made to the DOS32 version:
  - On Pentium and higher systems, floating-point calculations are now about 20% faster (and floating-point in exw is a further 20% faster than ex for 2.0).
  - printf() to the screen, and print() to the screen are both significantly faster in most cases.
  - The trace screen is updated a bit faster.
  - The time profile is more accurate regarding getc().
  - The mset.ex demo runs 30% faster.
