HP 250 - Selective Catalogs

System Commands
To obtain a catalog from a medium other than the mass storage
device, you can use either the unit specifier or volume label.
For example, if you wanted to see a catalog of the tape cartridge
located in the tape drive, you would execute the following
command:
CAT u:K"
You will then see a table listing of all files present on the
tape cartridge.
If you wanted to obtain a catalog of a volume labeled HP250 (it
could be any physical device), enter the following command:
CAT ",HP250"
Selective Catalogs
Suppose rather than obtaining a catalog of all files located on a
specific mass storage device, you wanted just a listing of all
files beginning with the letters HP or a listing of all type DATA
files on a mass storage device. You can do this by adding some
information to the CAT command.
For example, to obtain a listing of all files beginning with the
letters HP that reside on the default mass storage device, you
would enter the following command:
CAT "Hpu
To obtain a listing of all files that are type DATA on a flexible
disc, enter the following command:
CAT" :FIf )D('~TA
Finally, suppose you want to obtain a catalog listing of all
programs beginning with the letters HP that are type PROG and
reside on the 7908 fixed disc; enter the following command:
CAT ItHP:QIt,PROG
In all cases, the catalog is listed on the current system
printer. This is usually the display. To obtain a hard-copy
listing of a catalog, look at the section in this chapter on
output commands.
