BYTE

A one-byte unsigned integer.

 

Format: magnitude

      | ....... |

Bits:  7         0

Range: 0 to 255

 

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.

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.

BYTE declares a one-byte unsigned integer.

Example:

Count1 BYTE              !Declare one byte integer

Count2 BYTE,OVER(Count1) !Declare OVER the one byte integer

Count4 BYTE,DIM(5)       !Declare as a 5 element array

Count4 BYTE(5)           !Declare with initial value
