Q50496: The 37th Call Added to the Calls Menu Corrupts CodeView Screen
Article: Q50496 Product(s): See article Version(s): 2.20 | 2.20 Operating System(s): MS-DOS | OS/2 Keyword(s): ENDUSER | buglist2.20 fixlist2.30 | mspl13_basic Last Modified: 10-NOV-1989 The CodeView Calls menu shows the current depth of function calls as well as the line number the routine was called from and the parameters passed. The current routine is always at the top and the routine from which the current routine was called is directly below. The routines in the Calls menu are first labeled 0-9, and if you are nested more than ten levels deep, CodeView labels the next 26 calls A-Z, for a display that can accept 36 levels of subroutine calls. If you exceed this limit and then select the Calls menu, the CodeView display becomes corrupted. If the display is corrupted in this manner, the Redraw ("@") dialog command can be used to restore the display to it's original state. The Stack Trace dialog command (K) has the same function as the Calls menu and correctly handles nesting of more than 36 levels deep. Microsoft has confirmed this to be a problem with CodeView Version 2.20. This problem was corrected in Version 2.30.
