5 minus minus 6 on in HOME and CAS

[toml_12953]

A while ago, I was looking for a ++ and -- operator and was trying to create macros (where I discovered that define wasn't a macro generator but a short way to create a program)....but I was doing this to create my own decrement/increment functions....didn't know they already existed....
Also, decrement() and increment() aren't in the catalog.
These are functions that should run in home mode too....however, when I tried to run CAS.decrement(x), it got converted to decrement(5) and didn't decrement x in home mode.....is there a way to get decrement to work in home mode?
Thx

increment and decrement don't work at all for me, even in CAS mode.

a:=8
decrement(a)
gives
decrement(8) then when I display a, I still get 8.
