Can't get GZDoom to accept settings

[Thomas Songerforth]

I can't seem to get GZDoom to accept ANY command settings like DMFlags, Skill or Map through the shortcut and I can't figure out what I'm doing wrong.

Here's a simple one that's not working for me before I get too complex with my command line:
E:\Games\GZDoom\gzdoom.exe -file brutalv21.pk3 -file DoomMetalVol5.wad -host 2 -skill 4

--

The -host # part works. The part after does not. It always sets me to Skill 3. The same happens with any other setting I have attempted, and I'm not sure why: I've tried changing weapon stay, monster stay, map, etc. to no avail.

Is there something wrong with my syntax?

[_mental_]

To set console variables, you need to use +cvar value syntax, e.g. +skill 4.

-skill is most certainly a thing, though; the difference is that it sets the skill to x-1, e.g. -skill 4 means skill will be set to 3 (Ultra-Violence). +skill 4 is actually Nightmare.
