TIMEX OPERATING SYSTEM (TOS)


TOS is the operating system of the Timex FDD and FDD-3000 Systems.

This is a brief listing of the TOS commands and their meanings.  Arguments in square brackets ([])
are optional.  <> are used to represent a disk name/number file/ or pathname.


ATTR *
Syntax: ATTR * pathname P or U or I or V
P = Protect
U = Unprotect
I = hides file (invisible)
V = unveils file (visible)


CAT *
Syntax: CAT * [pathname]
Without the pathname, this displays information on files defined in the current directory.


CLOSE *x
Syntax: CLOSE *x expression
Closes the open file linked to the channel number given by the expression.


MOVE *
Syntax: MOVE * source-pathname TO destination-pathname
Copies a file or SCP (Serial Communication Port (RS-232)) to another file or SCP.


DIM *
Syntax: DIM * pathname
Creates file or directory specified by the pathname.


ERASE *
Syntax: ERASE * pathname [N]
Erases files.


FORMAT * (disk)
Syntax: FORMAT * drive-name TO disk-name
Formats disk currently inserted in drive specified. Destroys all files contained on the disk.


FORMAT * (SCP)
Syntax: FORMAT * SCP-pathname
If the string expression is a pathname designating a SCP, you can change the configuration of
that SCP.


GO SUB *
Syntax: GO SUB * [pathname] or GO SUB *"drivename"d
Saves the current directory in a special stack known as the "directory stack".  Used in
conjunction with DRAW * as an easy way of returning to the original directory.


GO TO *
Syntax: GO TO * pathname or GO TO *"drivename"d
Saves the current directory to the one designated by pathname.


INPUT *
Syntax: INPUT *#n; VAR$ [;AT p]
Reads a character or group of characters from a file or SCP via a channel.


LIST *
Syntax: LIST *
Lists information on the current directory and on all directories stored in the stack.


LIST *#
Syntax: LIST *# [channel number]
List information of the corresponding channel (if given), otherwise lists information on all
open channels.


LOAD *
Syntax: LOAD * pathname load-option
Very similar to the equivalent in Spectrum or Timex superset BASIC. The LOAD options are the
same.  The pathname can represent a SCP allowing you to receive BASIC programs (or code)
directly from another computer.


MERGE *
Syntax: MERGE * pathname
Merges a disk BASIC program to a program already existing in the computer memory.


LET *
Syntax: LET * old-pathname TO new-pathname
Renames a file, directory, or SCP.


OPEN #*
Syntax: OPEN #* expression 1;pathname;mode[expression 2]
Opens a file or SCP and associates a channel with it.


PRINT *
Syntax: PRINT *#n;STR$; [;AT P]
Writes characters or groups or characters to a file or SCP via a channel.


DRAW *
Syntax: DRAW * 
Used in conjunction with GO SUB * to retrieve directory information from the directory stack.


SAVE *
Syntax:  SAVE * pathname save-option [n]
Similar to Spectrum and Timex superset BASIC.  The options are the same.
