library 1...
define variable <no1>
type string
value <number 1>
display <>
end define

define variable <no2>
type numeric
value <0>
diplay <>
end define

library 2...

define variable <no3>
type numeric
value <1>
display <>
end define

now when I go into the game debug window in quest 3.0 it comes out with:
numeric
no2 = 0

string
no3 = number 1

and no1 has vanished

now when I remove no1 variable, for some reason variable no2 is undefined and no3 is in with the numerics! All these are in the !addto game bit of the library...
