Re: how to pass /E:ON argument to cmd.exe using exec (Windows)

Nothing to do with Tcl 8.6 either :-)
 From the DOS prompt:
D:\src\tcl-csv\library>cmd /C /E:ON dir
The filename, directory name, or volume label syntax is incorrect.
The /C needs to be before dir
D:\src\tcl-csv\library>cmd /E:ON /C dir
  Volume in drive D is DATA
  Volume Serial Number is 8245-4F72
  Directory of D:\src\tcl-csv\library
....

For a change of pace, this will not be a Tcl 9 question (I'm using 8.6.14).
 Using tclsh, why does this succeed:
     exec -- cmd /C dir
 but this fails:
     exec -- cmd /C /E:ON dir
 with this message :
     "The filename, directory name, or volume label syntax is incorrect."
 I'm guessing that "exec" is treating /E:ON as a file spec (the colon maybe?) and then changes it somehow.
 A followup question is how can I see what string is being presented to to Windows?
 Thanks for answering.
