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.

Example:

Count1 CLAULONG                        !Declare four-byte unsigned integer

 

Count3 CLAULONG,DIM(4)                 !Declare it an array of 4 unsigned longs

Count4 CLAULONG(5)                     !Declare with initial value

Count5 CLAULONG,EXTERNAL               !Declare as external

Count6 CLAULONG,EXTERNAL,DLL           !Declare as external in a .DLL

Count7 CLAULONG,NAME('SixCount')       !Declare with external name

ExampleFile FILE,DRIVER('Btrieve')  !Declare a file

Record       RECORD

Count8        CLAULONG,NAME('Counter') !Declare with external name
