Parameters

string string representing name of the variable.

Return Value

Success: the value of the variable.
Failure: "" (empty string) and sets the @error flag to non-zero.

Remarks

If there is a need to use Eval() to read a variable, then in most situations Assign() should be used to create/write to the variable and IsDeclared() should be used to check that the variable exists.
