Code the CALL following the syntax of the high-level language you are using and specifying all parameters in the order shown below. For parameters that CSRREFR uses to obtain input values, assign values that are acceptable to CSRREFR. For parameters that CSRREFR ignores, assign any value that is valid for the particular parameter’s data type.

Assign values, acceptable to CSRREFR, to object_id, offset, and span. CSRREFR ignores other parameter values. CSRREFR returns values in return_code and reason_code.

object_id

Specifies the object identifier. Supply the same object identifier that CSRIDAC returned when you obtained access to the object.

Define object_id as character data of length 8.

,offset

Specifies the offset into the object in blocks of 4096 bytes. A value of 0 specifies the first block of 4096 bytes or bytes 0 to 4095 of the object; a value of 1 specifies the second block of 4096 bytes, or bytes 4096 to 8191 of the object, and so forth.

Define offset as integer data of length 4.

offset and span, together, determine which part of the object window services refreshes. To refresh the entire object, specify 0 for offset and 0 for span.

,span

Specifies how many 4096-byte blocks CSRREFR is to refresh.

Define span as integer data of length 4.

,return_code

When CSRREFR completes, return_code contains the return code. Define return_code as integer data of length 4.

Return codes and reason codes are explained under Return codes and reason codes.

,reason_code

When CSRREFR completes, reason_code contains the reason code. Define reason_code as integer data of length 4.

Return codes and reason codes are explained under Return codes and reason codes.
