If omitted, the initial value is zero, unless the AUTO attribute is present. | | **DIM** | Dimension the variable as an array. | | **OVER** | Share a memory location with another variable. | | **NAME** | Specify an alternate, "external" name for the field. | | **EXTERNAL** | Specify the variable is defined, and its memory is allocated, in an external library. Not valid within FILE, QUEUE, or GROUP declarations. | | **DLL** | Specify the variable is defined in a .DLL. This is required in addition to the EXTERNAL attribute. | | **STATIC** | Specify the variable's memory is permanently allocated. | | **THREAD** | Specify memory for the variable is allocated once for each execution thread. Also implicitly adds the STATIC attribute on Procedure Local data**.** | | **AUTO** | Specify the variable has no //initial value//. | | **PRIVATE** | Specify the variable is not visible outside the module containing the CLASS methods. Valid only in a CLASS. | | **PROTECTED** | Specify the variable is not visible outside base CLASS and derived CLASS methods. Valid only in a CLASS. | **SIGNED** declares a signed integer which is a LONG. The SIGNED data type is most useful for prototyping Windows API calls. **Example:** **Count1 SIGNED   !Declares a LONG**
