Programming a BEA Tuxedo Application Using COBOL

The TPTYPE-REC COBOL structure is used whenever sending or receiving application data.

The following table lists the TPTYPE-REC structure fields.

Field
Description

REC-TYPE

Specifies which record type the application wishes to send or receive.

SUB-TYPE

Specifies the subtype of the record type, if further classification is required (as it is, for example, in a VIEW record).

LEN

When data is being sent, specifies the number of bytes to be sent. After a successful transfer, LEN contains the number of bytes transferred. When data is being received, LEN in TPTYPE-REC specifies the number of bytes to be moved into the data record. After a successful call, LEN contains the number of bytes moved into the data record. If the size of the incoming message is larger than the size specified in LEN, the data is truncated, all data after the LEN length is reached is discarded, and TPTYPE-STATUS is set to TPTRUNCATE.

Field	Description
REC-TYPE	Specifies which record type the application wishes to send or receive.
SUB-TYPE	Specifies the subtype of the record type, if further classification is required (as it is, for example, in a VIEW record).
LEN	When data is being sent, specifies the number of bytes to be sent. After a successful transfer, LEN contains the number of bytes transferred. When data is being received, LEN in TPTYPE-REC specifies the number of bytes to be moved into the data record. After a successful call, LEN contains the number of bytes moved into the data record. If the size of the incoming message is larger than the size specified in LEN, the data is truncated, all data after the LEN length is reached is discarded, and TPTYPE-STATUS is set to TPTRUNCATE.

The following shows the TPTYPE data structure:

05 REC-TYPE PIC X(8).
  88 X-OCTET VALUE "X_OCTET".
  88 X-COMMON VALUE "X_COMMON".
05 SUB-TYPE PIC X(16).
05 LEN PIC S9(9) COMP-5.
  88 NO-LENGTH VALUE 0.
05 TPTYPE-STATUS PIC S9(9) COMP-5.
  88 TPTYPEOK  VALUE 0.
  88 TPTRUNCATE VALUE 1.
