When CodeView for Windows (CVW) is running in version 3.1 of the Microsoft Windows graphical environment, CVW does not trace into the subprograms of an application written in FORTRAN and compiled as a QuickWin application. The Step Into key (F8) acts as a Step Over (F10) and skips to the instruction that follows the current routine.


Place a break point in the desired subprogram and continue execution. CodeView halts execution at the breakpoint as desired.


Microsoft has confirmed this to be a problem in CodeView versions 3.06, 3.07, 4.0, and 4.01 for Windows. This problem was corrected in CodeView version 4.1 for Windows.


In the sample code below, select the print statement and press the F9 key to set a break point. Use the F10 key to step through the code. CodeView stops on the print statement in the sub1 subprogram.

Sample Code

C --------------------------------------
C compile options: /MW /Od /Zi
C --------------------------------------

      call sub1()

      subroutine sub1()
      print *,'Inside sub1'
