FIX: Deleting Current Makefile in PWB 1.0 Causes R6000 Error

The information in this article applies to:

• Microsoft Programmer's Workbench for MS-DOS, version 1.0
• Microsoft Programmer's Workbench for OS/2, version 1.0

SYMPTOMS

If you are viewing your makefile in a window in the Programmer's WorkBench (PWB) version 1.0 and then delete the makefile from a shell, attempting to make the window containing the makefile active will cause a run-time error R6000, stack overflow.

STATUS

Microsoft has confirmed this to be a problem in PWB version 1.0. This problem was corrected in PWB version 1.1.

MORE INFORMATION

To duplicate this problem, bring up a sample program and set the program list to that file's makefile. Next, open up another window and open the makefile in that window. Now, delete that makefile either by choosing Run <DOS-OS/2> Command from the Run menu, or by choosing the <DOS-OS/2> Shell from the File menu.

After returning back to the PWB, make the window containing the makefile the active program list either by pressing the F6 key to toggle windows or by clicking the left mouse button in that window.

You will be faced with a pop-up message saying "File has been deleted from disk. Delete from memory?" Answering "yes" brings up the pop-up message six to eight more times. Then, PWB will abort to the system prompt with an R6000 (stack overflow) error message and another message, "File has been deleted from disk."
