MICRODRIVE USE
The program is loaded from the cartridge in Microdrive. You must always make sure that
before using Help or using a print command that this cartridge is in Microdrive 1.
Otherwise you can remove the cartridge at any time.
Use a cartridge in Microdrive 2 - and in additional Microdrives - for storing information, for
example, Quill documents, Archive data files, etc.
FILE NAMES
Information can be stored on a cartridge in a file. The file must be given a file name to
distinguish it from others on the cartridge. Use a file name of not more than eight
characters long, without spaces. It is a good idea to use a name which describes the
contents of a file for instance sales is obviously a better name for a file of sales figures
than fred.
File saving and loading will use a data cartridge which is assumed to be in Microdrive 2
unless a different drive number is given. The simplest way of replying to a file name
request is just to type in the name by itself, for example
which automatically accesses Microdrive 2. If you wanted to access Microdrive 1 you
would type:
There is a third component of a file name which you do not usually see because it is
automatically added by the program. This is an extension three letters long which identifies
which program saved the file. The extensions used are:
QL Quill
QL Abacus
QL Easel
QL Archive (data file)
QL Archive (program file)
QL Archive (screen layout)
