delassoc

delassoc <list> <key> [<foundvar> [<elvar>]]

Examples:

"delassoc $val murphy": Returns $val without the sublist whose first element is the string "murphy."

Deletes an entry from an associative list.

<foundvar>, if given, is the name of a variable in the caller's scope that is to be set non-zero if an element in <list> was found whose <key> matched the given one. If no such element was found (and therefore deleted), the variable is set zero.
<elvar>, if given, is the name of a variable in the caller's scope that receives the element that was deleted from the list. If no element was deleted, the variable remains untouched.

See Also: assoc.

detach

detach [<options>]

Examples:

Detach swat from the PC.

The <option> argument may be one of the following: continue : continue GEOS and detach swat; leave : keep GEOS stopped and detach swat. Anything else causes swat to just detach.

See Also: attach, quit.

dirs

Prints the directory stack for the current thread.

See Also: pwd, stdpaths.

discard-state

Examples:

"discard-state": Throw away the values for all the thread's registers as saved by the most recent call to save-state .

Throw away the state saved by the most-recent save-state command.

This is usually only used in response to an error that makes it pointless to return to the point where the save-state was performed.

See Also: save-state, restore-state.

diskwalk <drive>

Examples:

Prints out the information on registered disks.

The Flags column is a string of single-character flags with the following meanings:

w: The disk is writable.
V: The disk is always valid, i.e. it's not removable.
S: The disk is stale. This is set if the drive for the disk has been deleted.
u: The disk is unnamed, so the system has made up a name for it.

See Also: drivewalk.

display <lines> <command>
display list
display del <num>

Examples:

Manipulate the display at the bottom of Swat's screen.

If you give a numeric <lines> argument, the next argument, <command>, is a standard Tcl command to execute each time the machine halts. The output of the command is directed to a window <lines> lines high, usually located at the bottom of the screen.
You can list all the active displays by giving "list" instead of a number as the first argument.
If the first argument is "del", you can give the number of a display to delete as the <num> argument. <num> comes either from the value this command returned when the display was created, or from the list of active displays shown by typing "display list".

See Also: wtop, wcreate.

dosMem

Examples:

down [<frame offset>]

Examples:

Move the frame down the stack.

The frame offset argument is the number of frames to move down the stack. If no argument is given then the current frame is moved down one frame.
This command may be repeated by pressing <Return>.

See Also: backtrace, up.
