George,

It is not a bug and it is in accordance with the docs. The TYPE() function returns the data type for an expression, any expression.

TYPE("12x12") = N
TYPE(FOUND()) = L
etc.

So when we do;

Var = "12345"
TYPE(var)

we are gfetting teh type of the contents of var which is numeric, the type of the variable named var is character (note the quotes in the assignment line).

Another method that would work is;

STR(VAL(Var),LEN(Var)) = Var

Although some numeric strings would fail the test.

VarType() would not work here because it is the value inside the var that Nadya wants the type for, not the var itself.
