I ran into this issue while looking for a workaround to the dbvar/#ADD problem I reported earlier.

The command #VAR test.one @test.one-1 results in @test.one being set to a null value instead of reducing the value by one.
I was dumbfounded but then realized it assigns to @test.one the contents of the nonexistent variable @test.one-1 instead of parsing - as the subtraction operator. Easily verified if you actually create the one-1 entry.

A simple enough workaround of a workaround is #VAR test.one %eval(@test.one)-1, but this was definitely unexpected behavior. + / * appear to work properly.

Also vaguely under this same topic, didn't want to post separately for this... the modulus operator of zMUD, \, doesn't appear to work - not implemented at all? Will it be? Of course possible to use %mod(), just wondering.

\ isn't implemented
I'd also like to see ^ for exponents.

Added to bug list, but to force expression evaluation, you can just put () around the expression:

#VAR test.one (@test.one-1)

#VAR test.one (@test.one-1) also experiences this problem, as does #VAR test.one %eval(@test.one-1) which is something I tried originally. But akin to %eval(@test.one)-1, (@test.one)-1 does work, indeed.
