This appears to be "the exception that proves the rule":
    
https://en.wikipedia.org/wiki/Exception_that_proves_the_rule#Original_meaning

According to Cicero, this means that if VOL *is* specified on the FROM 
parameter,
the "file" need not be catalogued.  Must FROM and TO refer to the same dsn?
If so, wouldn't it be copying a data set over itself?  Or might "file" be a 
different
member of the same PDS(E)?
