If using either the DLL or COM based interface, it is important to understand how the ATI is initialized with respect to referencing account names. The ATI is initialized to the first account name used in the first calling function.
Some functions accept an account name as a parameter. In most if not all functions, these parameters can be left blank in which case the "Default" account as specified under the Tools-->Options window of the Control Center window will be used. If your default account is set to 'Sim101' and you call functions and leave the account parameter blank, you the Sim101 account will be automatically used.
Example:
Default account = Sim101
A function call is made with "" empty string as the account name argument
Sim101 account is automatically used
Subsequent function calls must use empty string if you want to reference the Sim101 account
If you call a function and pass in the argument "Sim101", invalid information will be returned
