The program selector can support up to 54 items in its menu.
(The limit is 48 for the 40-column version).
The SAVE option uses a file to store the program selector menu
in. This file is named PROSEL.80 or PROSEL.40 depending on
your screen sire. There are only 2600 bytes in PROSEL.80 and
2900 bytes in ProSel.40 in this file. If adding or editing an ex-
isting entry results in the sum of the data in the file exceeding its
limit, the excess will be deleted. If your needs require a large
number of titles in the program selector, you should use modest
lengths for each. Editing existing titles can also reduce the over-
all size of the program selector file.
Then using the 40 column version of ProSel, as you exceed 46
“program selector” menu items, the next 2 entrees may not dis-
play properly. The only remedy is to use the 80 column version.
REMARKS
Some application programs may not support the ProDOS “quit
protocol”. Apple’s own CONVERT is such a program. If, like
CONVERT, they allow quitting via a direct specification of path-
name, to accomplish this specify the pathname
/MYVOL/PROSEL.SYSTEM, which will invoke the program
selector. The reason for this non-support is that these programs
were written while ProDOS was still being developed and did
not yet have a well defined quit procedure.
It is possible to have BASIC.SYSTEM 1.1 on one directory and
have it boot a startup program in a second directory. The follow-
ing is an example of this:
Screen title: MYPROGRAM
Prefix: /HARD1
Pathname: BASIC.SYSTEM
Startup: /HARD2/MYPROGRAM
In this example, BASIC.SYSTEM would be loaded from the
volume: /HARD1 and would run the program: MY PROGRAM
in the volume: /HARD2. Using this technique, you would not
need to have the BASIC.SYSTEM in both volumes.
