FCOPY Functions

SKIPEOF

Figure 5-6. Skipping Absolute File Numbers

If you specify zero as a

from-file-number

or a

to-file-number

, FCOPY copies from or to

the ﬁrst ﬁle on the tape or serial disk.

Relative File Numbers

Both

from-eofs

and

to-eofs

represent the number of ﬁles to skip relative to the tape's

current position. If you use a plus sign (+) to specify forward movement, the SKIPEOF

function skips forward over the speciﬁed number of EOF marks. Figure 5-7 shows the effect

of specifying SKIPEOF=+3.

Figure 5-7. SKIPEOF=+3

If you use a minus sign (−) to specify backward movement, the SKIPEOF function skips

backward over the speciﬁed number of EOF marks plus 1, and then skips forward one EOF

mark. This action positions the tape at the beginning of a ﬁle, rather than at the end of the

preceding ﬁle. Figure 5-8 shows the effect of specifying SKIPEOF=−3.
