 Last reviewed: May 19, 1997
Article ID: Q157745
The information in this article applies to:
  • Microsoft Windows NT Workstation version 4.0
  • Microsoft Windows NT Server version 4.0

SYMPTOMS

When you run CMD or BAT files that use the Windows NT command extension syntax, access violations in Cmd.exe may occur.

For example, create the following Test.cmd file: 

   FOR /R C:\ %%f in (iexplore.exe, patchdll.dll, srv.sys) do if exist %%f
   echo %%f
An error message will be displayed: 

   Application Error: The instruction at "0x77f646ce" referenced memory at
   "0x0073006f". The memory could not be read.
NOTE: The address values may be different on your system.

Results may vary, depending on what group of files is contained in the set. A Dr. Watson error may be one such occurrence. Usually, there is no error if the set contains only a single file.
