#403 4.20: Command line error: filename begins with minus

[Anonymous]

Hello. Thank you for the nice archiver!

This is the listing from stdout:
---------

7za a -t7z arc -file.txt -r0 -m0=LZMA:d8m -mx=9 -ma=2
-y

Error:
Incorrect command line

---------
It seems to me that the incorrection happened because
the file name begins with the minus. When I had added
quotes around -file.txt it didn't work as well. Is it a
feature or a bug?

Use two minus signs to signal the end of switches

e.g.
D:\tmp> 7z a -mx=9 -- sfile.7z -sqldps.rpt
