Can we use /MAKE inside the popen3 command?

[Ruchika]

Is it OK to use "/" or "-" characters in a string and then use that
string inside the popen3 command? I am doing the following -

os.popen3('r'"C:\Program Files\... \EVC.exe"'
r'"C:\Test\...\Test.vcp"' /MAKE "GFSDK - Win32 (WCE ARMV4) Release"
/REBUILD"')

When I run this command in the Python shell, it says - "Syntax Error"
and the marker is uderneath the "-" in  "GFSDK - Win32 (WCE ARMV4)
Release". Not sure if the marker is actually pointing to specifically
"-" or the entire /MAKE "GFSDK - Win32 (WCE ARMV4) Release" string.
Anyone else came across similar problem?

Thanks for your help.
