Tanker Accessory WFL
You can modify the WFL/DATABRIDGE/TANKER file for the following:
Tanker Accessory TASKVALUEs
WFL/DATABRIDGE/TANKER also includes support for reporting the success or failure of the Tanker Accessory. To do so, the Tanker Accessory sets its TASKVALUE to the last error message number.
When the Tanker Accessory encounters any errors, whether from DBEngine (1–899), the Support Library (1400–1499), or encountered directly (900–999, 1800–1899), it returns the number as a positive value in its TASKVALUE. These error numbers are listed in Appendix A, “Messages."
In WFL/DATABRIDGE/TANKER, the TASK is defined as TANKER and the value is returned as TANKER (VALUE). Following is sample WFL code that displays the TANKER (VALUE):
DISPLAY "TANKER TASKVALUE = +" & STRING(TANKER(VALUE), *);
