label CLAULONG([initial value]) [,DIM( )] [,NAME( )] [,EXTERNAL] [,DLL] [,STATIC]


CLAULONG A four-byte unsigned integer.

Format:     magnitude


Bits:  31                  0

Range: 0 to 4,294,967,295

initial value A numeric constant. If omitted, the initial value is zero, unless the AUTO attribute is present.
DIM Dimension the variable as an array.
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.

CLAULONG declares a four-byte unsigned integer, using the Intel 8086 long integer format. There is no sign bit in this configuration.
