INSPEC is a program to look into sectors of floppy or hard disks,
and into files, especially if they contain numbers instead of
ASCII text. It can also be used to show FAT 1 and 2 of any standard
device. INSPEC accesses all data via GEMDOS or BIOS calls.
It is NOT a disk monitor, it allows only listing (also on a protocol
file), but no changing of the data in a file or at an absolute position
of a disk.
INSPEC is key-driven. The meaningful keys are always displayed, and a
short explanation is given, when the ? key is pressed.
The I key ("interpret") allows interpreting directory sectors, floppy
& harddisk boot sectors, and changing display format (integers, MS-DOS-
integers...) in a separate menu. The Q key ("quit") returns to
the main menu and from there to the shell (desktop).
Useage:
1) activate the program INSPEC.TOS (from desktop or other shell)
2) when prompted, give a protocol file name (may be PRT: for
immediate printing), or press RETURN to get output on display
screen
3) when prompted for a file name, enter the name of the file to be
inspected. If you don't want to see a file, but rather some
sectors of a device, simply press RETURN without entering a name.
You will the be prompted for a device letter (small or capital,
a = 0 = floppy A:, c = 2 = RAMdisk or harddisk C: etc.)
Press any valid keys, e.g. N to see the next part or sector, or S to
select the starting point for display. Change to other file (F) /
drive (A) / FAT listing (T) / directory listing (D). The S key selects
the sector number in A (drive) mode, the byte offset in F (file)
mode, and the first allocation unit in T (FAT) mode.
The display format is chosen to fit one sector on one screen.
The characters in dump format (hex plus some characters shown,
others represented by a period) are chosen to be printable on most
available printers; if you want to see all characters, use character
format (I C).
Within directory listings (D) or directory sector interpretation (I D),
the flags mean
S = system file
H = hidden file
D = subdirectory
V = volume label
C = written & closed flag (not properly used by GEMDOS)
R = read-only file
also file size and creation date (European format) are given.
In a directory sector, in addition the first AU number and the
(unused) flag array is listed.
FAT listings (T) of both 12 and 16 bit FATs are possible. An FAT
entry is a pointer to the next AU of a file. -1 means EOF, 0 is an
empty AU. Other negative numbers signal bad sectors.
N.B. AU 0 and 1 are reserved, the first data sector is in AU 2.
Finally, you may copy the program and use it, but I take no liability
for any result, and you must not make profit from it without my
written consent.
