To maintain portability with the UNIX text system, I'm using a MS-DOS box for STDOUT.  But unlike UNIX, DOS doesn't have a scrollback bar.  Is there a way around this so that when I run a program in VC++, I can see more than 25 lines of output??

You may consider to direct your output to a CEdit control. In your VC++ project, create a CEdit control with scroll bar in the CFormView. Each line of printf()is substituted by a code looks like this:

        m_pView->m_cEdit.SetSel(0x7FFF, 0x7FFF);
      sprintf(text, "your output string\r\n");
      m_pView->m_cEdit.ReplaceSel(text, FALSE);

m_pView is the pointer of your current view. m_cEdit is the variable of the CEdit control. USing SetSel(0x7FFF, 0x7FFF)to select the portion after the last character of the CEdit. Using ReplaceSel() to write the string to the CEdit. Do not forget to add "\r\n". Also encapsulate your UNIX program into a class. Since the CEdit control has scroll bar, you can see the whole content of your output.

Hope it will be help.
