SEARCH OPERATIONS ON THE SECOND DISK
The following procedures are used to search on disk 2:
1.
2.
3.
4.
Press FUNCT SEL lower.
Hold down the NUM SHIFT key and press SEARCH
CONTENT, SEARCH. SEa CONTENT, or SEARCH
ADDRESS.
Press FUNCT SEL lower and DELETE to clear the
display and key the search data or address.
Press FUNCT SEL upper and then DISK 2 REC ADV.
After the first content search, subsequent searches by
content using the same search mask can be accomplished as
follows:
1.
2.
Press FUNCT SEL lower, hold down NUM SHIFT,
and press SEARCH CONTENT.
Press FUNCT SEL upper and DISK 2 REC ADV.
COpy
Copying is always done from disk 2 to disk 1.
Copy All or Part of Disk 2
This copy function copies disk 2 onto disk 1, beginning
with the sector in track 00 where disk 1 is positioned. The
last record is copied from the sector located at the end of
extent (EOE) of the label at which disk 2 is positioned at
the start of the copy function.
Each record is copied into the corresponding track and
sector address; that is, the record from track 02, sector 14
of disk 2 will be copied into track 02, sector 14 of disk 1.
All records will be copied regardless of content, including
deleted records, records outside of defined extents, and
normal data records between the beginning of extent (BOE)
and the end of data (EOD).
To copy disk 2 to disk 1, do the following:
1.
I nsert the disk to be copied from in the disk 2 drive.
2.
Insert the disk to be copied onto in the disk 1 drive.
38
3.
Position disk 1 on the index track to the sector where
copying should begin. For a full disk copy, position
the disk to sector 01.
4.
Position disk 2 to the label that contains the end of
extent (EOE) where copying is to stop. For a full
disk copy, position to the label with the highest
value of EOE.
5.
Press FUNCT SEL upper; then hold down NUM
SH I FT and simultaneously press COpy (starts the
copying operation).
6.
When copying is completed, press FUNCT SEL lower
and then RETURN TO INDEX.
Copy All or Part of a Data Set
The primary purpose of this function is to pool data from
two or more disks onto one disk by adding data from disk
2 to the end of the data already recorded on disk 1. A
sequence of such copies can involve loading several disks
into the disk 2 drive and pooling the work of several opera-
tors onto one disk. Deleted records are not copied.
To copy all or part of a data set, do the following:
1.
Insert a disk in the disk 2 drive.
2.
3.
4.
5.
6.
Insert a disk in the disk 1 drive.
Position disk 1 at the address where copying is to
begin by either:
a. Pressing FUNCT SEL lower, then ENTER to
position disk 1 at the beginning of extent (BOE).
b. Pressing FUNCT SEL lower, SEARCH EOD, and
REC ADV to position disk 1 at the end of data
(for pooling).
Position disk 2 on the label of the data set where
copy is to begin or on the first record to be copied.
Press FUNCT SEL upper; then hold down NUM
SHIFT and press COpy. Copying stops when the last
record in the data set has been copied.
When the copy operation has finished, press FUNCT
SEL lower, then RETURN TO INDEX.
