New Features and Other Changes
SLEEP statement supported for CMS
SLC will then read the file "abc.data" off any accessed disk, or failing that, off the BFS or HFS (Byte File System for CMS or
Hierarchical File System for MVS), and take 10 seconds to process each record. Very useful !
Alternatively, a SLC job could be started which re-accessed a disk, checked for the existence of a certain file or event and did
something useful, otherwise sleeps for 20 mins or whatever. It could be left running continuously in a disconnected machine. e.g.
selcopy POSIX(ON) / -ctl=CHECKEML.CTL
-Lst=EMAIL.LST.B

FLUSH statement support for TAPE output
All SELCOPY's output files are buffered using a buffer of length BLKSIZE, default=2048.
Nothing is physically written until the buffer cannot accommodate another record, at which time the buffer is written out, reset to
empty, then used for the record that wouldn't fit.
The FLUSH statement allows the user to control when SELCOPY issues a physical write in order to clear the buffer.
For output to a real TAPE device, the physical write will also include the writing of an Inter-Record-Gap on the tape, so the FLUSH
statement becomes very important in order to control where the IRGs occur. e.g.
read input.fil
wr
tape.fil
flush tape.fil
* Read a data record.
* Puts curr record in buffer.
* Physically writes and clears the buffer.
Note:
1. SELCOPY's OPEN=NORWD and CLOSE=NORWD will have no effect. If coded they are silently ignored.
However, when attaching a tape to a UNIX or PC system, you may well find that an option exists for choosing whether at
open/close time the tape rewinds or remains where it is.

NEWBLK param to give equivalent of FLUSH
The NEWBLK parameter may be used on a WRITE statement to give the same effect as using a FLUSH statement prior to the
WRITE. e.g.
read input.fil
wr
tape.fil newblk
* Read a data record.
* Puts curr record at start of buffer,
* by first flushing the buffer if reqd.
* Thus, every record will start a new block.
* Other WRITE statements may be coded, without the NEWBLK param,
* if selective blocking is reqd.
