| -- OBJECTIVE: |
| -- CHECK THAT RESETTING ONE OF A MULTIPLE OF INTERNAL FILES |
| -- ASSOCIATED WITH THE SAME EXTERNAL FILE HAS NO EFFECT ON ANY |
| -- OF THE OTHER INTERNAL FILES. |
| |
| |
| -- APPLICABILITY CRITERIA: |
| -- THIS TEST APPLIES ONLY TO IMPLEMENTATIONS WHICH SUPPORT MULTIPLE |
| -- INTERNAL FILES ASSOCIATED WITH THE SAME EXTERNAL FILE AND |
| -- RESETTING OF THESE MULTIPLE INTERNAL FILES FOR TEXT FILES. |
| |
| -- HISTORY: |
| -- DLD 08/16/82 |
| -- SPS 11/09/82 |
| -- JBG 06/04/84 |
| -- EG 11/19/85 MADE TEST INAPPLICABLE IF CREATE USE_ERROR. |
| -- TBN 11/04/86 REVISED TEST TO OUTPUT A NON_APPLICABLE RESULT WHEN |
| -- FILES NOT SUPPORTED. |
| -- GMT 08/25/87 COMPLETELY REVISED. |
| -- EDS 12/01/97 ADD NAME_ERROR HANDLER TO OUTPUT NOT_APPLICABLE RESULT. |
| -- RLB 09/29/98 MADE MODIFICATION TO AVOID BUFFERING PROBLEMS. |
