Library Commands
D. Do not keep a capture file any longer than necessary so that the space on the
disk may be used for another capture file. The default, when printing out a
captured file, is for the captured file to be deleted upon completion of the
printing.
E. Try to avoid the outputting of large number of spaces in a printed report. If at
all possible, use the tab character
(X'09')
instead of spaces, to "position" to
the next printed column or field. The capture file will only have to store the
single tab character instead of the spaces. This will save on disk storage
space.
F. You might be able to move some of your data files from one disk to another
(in a multi-drive system) to free up the largest amount of disk space onto a
single disk for the capture file. This could slow down your other disk
accesses, depending on a lot of other factors, but this still might be faster just
because of using the capture function instead of a real, "physical" printer.
Some applications, because of the amount of free space on the disks, or
because of the size of the printed reports, will preclude the use of spooler.
Sample runs should show you what disk space requirements you might have
and what limitations of printed report size you might experience.
I O. Spooler (either capture or printing) is compatible with:
A. Host
B. Serial Printer
(SETCOM, FORMS S)
C. Do File Processing
D. Dual Routing
E.
LIB
commands
PRT
option
(DIR, FREE, ANALYZE, LIST)
F. Communications (Some timing diffIculties might be experienced at
higher baud rates)
G. Most utilities and
LIB
commands
11. Spooler should never be run when formatter, or backup is running. In addition,
the disk that has the capture file on it should never be removed from the drive
until that capture file is closed and/or spooler is de-activated. Keep in mind that
when a printing function is currently in progress, the disk with the file being
printed must not be removed from the drive it is in, until the file is closed (and
deleted, if so desired). Depending on what else is going on, sometimes the
print file will remain open for several minutes after the printing has been
completed. Make sure by doing a directory, looking for the print file in the
DIR
before removing the diskette. The print file will not appear in the directory
with a"?" next to the name, because it was only opened for reading, not for
writing. Only fifes opened for writing will have this"?" appear in the
DIR
listing.
