Overriding Defaults
Two options for SLTCOPY are provided to allow additional control over the utility. The options are
INFO=NOWAITIO and INFO=WAITIO. You only need to use these options if you want to override the SLTCOPY
defaults.
To override the defaults, you should be very familiar with MPE/iX I/O operations.
WAITIO causes SLTCOPY to wait to send the next buffer until it receives an acknowledgment from the system
that the last buffer has been written to tape. NOWAITIO tells SLTCOPY not to wait for the acknowledgment
before sending the next buffer. This option is useful (and is the default) when creating multiple output tapes.
It allows SLTCOPY to create multiple tapes virtually simultaneously.
To override the defaults listed in Table E-1, you invoke SLTCOPY as follows.
If making one copy and wanting to use the NOWAITIO option, invoke SLTCOPY as follows:
:RUN SLTCOPY;INFO=“NOWAITIO”
You then respond 1 when SLTCOPY requests the number of copies.
If making multiple copies all at once and wanting to use the WAITIO option, invoke SLTCOPY as follows:
:RUN SLTCOPY;INFO=“WAITIO”
You then specify the number of copies you want to make when SLTCOPY requests the number of copies.
NOTE Remote file access is not permitted for output tapes if the NOWAITIO option is in effect.
