When it was pointed out by appellants, at page 6 of the principal brief, that Coker may teach the interchangeability of file systems for use in conjunction with COBOL programs but it does not teach the use of source language statements, acting as compiler directives, to identify the desired file system, the examiner’s response was to change course and now hold, in the answer, that it is really appellants’ admitted prior art [from page 2, line 11, through page 3, line 11, of the specification] that taught this feature.
