Issue with Defined User function (in FW 7820)

[salvomic]

for now I made another try in Emulator:
there was the last variable (created with Define), named "ramp", I had changed its value in 14;
I created a new function with Define: "gigi" as "X+1"
refreshed the Emulator via CK
I had two variables: ramp -> 14, gigi -> Error object...
deleted "ramp" via DelHVars("ramp")
ok, it remains "gigi", also after close and restart, or only after the refresh.

Conclusion: we can delete every variables, but not the last one.
