ISOBJECT function

Purpose | Determine the current status of a given object variable.
Syntax | oStatus = ISOBJECT(objectvar)
Remarks | ISOBJECT is particularly useful in determining the success or failure of a LET (with Objects) statement. It returns TRUE (-1) if the object variable contains a valid current reference to an object interface, or FALSE (0) if it contains nothing. ISOBJECT is the complement to the ISNOTHING function.
Restrictions | objectvar must be an interface or IDispatch object variable.

Example | DIM oApp AS IAPPDatabase LET oApp = NEWCOM "DBApp.0" IF ISOBJECT(oApp) AND ISFALSE ERR THEN 'Handle error
