The following code works differently according to a combination of launch method and bitness;

Code:

      i=winio$('%ww[no_border,no_maxbox]&')
      i=winio$('%ca[window caption]&')
      i=winio$('%pv&')
C *** At present under 64 bit when launched by double clicking, this crashes.
      i=winio$('%53.10cw[hscroll,vscroll]&',2)
      i=winio$('%hw',information)


Works:
32 bit - launched from cmd
32 bit - launched from double click
64 bit - launched from cmd

Fails with a silent process exit:
64 bit - launched from double click

I'm guessing that ClearWin sets the default I/O units up differently between 32 and 64 bit. Another guess is that by running from a command prompt the default units are initialised somehow, bypassing the double click bug.

Can anyone throw any light on this behaviour?

Regards

Ryan

Thank you for the feedback. I will make a note that this should be investigated.

Your code works for me but it may be because I am using the latest DLLs.
Issues relating to %cw have been raised elsewhere and have been fixed.

Here is my version...

Code:
      winapp
      integer i,winio$
      integer,external::start
      integer(7) information
      i=winio$('%ww[no_border,no_maxbox]&')
      i=winio$('%ca[window caption]&')
      i=winio$('%sc&', start)
      i=winio$('%pv&')
      i=winio$('%53.10cw[hscroll,vscroll]&',2)
      i=winio$('%hw',information)
      end

      integer function start()
      write(2,*) 'Hello'
      start = 2
      end function


The latest beta release may have the relevant fixes. See
