program selector. If you want to control the order in which
menu items appear, use leading control characters in the
title. Control characters are allowed in the titles (and not
shown except when editing the title) they can be used to force
the sorting to place the items in what appears not to be
alphabetical order. Thus, if there is a group of applications
you want to appear first in the list, just start their titles name
with a control-A, etc. You cannot use control H or U or
others that would be intercepted by the firmware on input.
PREFlX This is needed to describe where the application
program is saved on your disk. In the case of the Sider the
root directory’s prefix is /HARD1 (unless user modified).
Most applications would be in sub-directories, not in the
root. In entering the prefix you would enter both the root
directory and the appropriate sub-directory(s) as follows.
EXAMPLE:
Prefix /HARD1/PROGRAMS
(root+1 sub-directory)
or
Prefix /HARD2/ACCNT/COST (root+2 sub-dIrectorIes)
The editor automatically adds the “/” to the end of the
prefixes you supply. The prefix must be a valid full path-
name and the application file must be of SYS type. If the
entry is not a SYS type it will cause an error. The editor,
however, will have no knowledge of this. The startup file
may be of any type supported by the interpreter. Presumab-
ly, BASIC.SYSTEM 1.1 would support any file for which
the -“ syntax is acceptable.
In prefixes, pathnames and startup names, the character”?”
can be used as a substitute for the volume name (INCLUD-
ING “/” ON BOTH ENDS) containing the active ProSel file.
There are two reasons for this convention. The obvious one
is that it saves a great deal of space in the application list.
The other, mainly applicable to 800K drives, is that it allows
disk swapping.
