the source files appeared in the catalog as "L" if you booted LISA, or "B" if

you booted a normal disk.

The "B", "A", "R" and "S" special file types cannot be accessed by BASIC

programs (unless you patch DOS) - commands are only provided for dealing with

"B", "A", "I" and "T" files.

The four special types can only be accessed using direct calls to the File

Manager.

014- What do the entries in a DOS 3.3 Catalog display

mean?

A standard DOS 3.3 Catalog display looks something like this:

DISK VOLUME 254

*A 002 HELLO

B 033 TETRA/SOFT LOGO.BIN

T 142 DAVE'S LIST OF DOS COMMANDS

I 002 INTEGER BASIC PROGRAM

^^ ^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

|| ||| ||||||||||||||||||||||||||||||

|________________________________________* means the file is locked

015- How long can a DOS 3.3 file name be and what

characters can it include?

DOS 3.3 filenames may be up to 30 characters long, and must conform to the

following restrictions:

a. The first character must have an ASCII code value greater than 63. This

excludes numerals, SPACE, and most punctuation. The "@" character is allowed as

well as letters, and some special chars such as "]", "~", "_", and a few others.

b. Commas and colons may not be used at all. Apart from these restrictions,

anything goes. All kinds of characters, including uppercase, lowercase, numbers,

symbols, and CONTROL characters can be used after the first character.
