On direction, you specify the direction of reference through the array. Forward reference means instructions start with the element indicated by low_address and proceed through the range of data specified by size. Backward reference means the program starts processing the high-address end of the range specified by size and proceeds toward the low_address end.

• "+1" indicates forward direction.
• "-1" indicates backward direction.

An example of forward reference through ARRAY1 is specified as follows:

CSRIRP  with direction of +1
