In IEEE1275 (there are also examples in how it's used scattered 
throughout the spec).

my-args ( -- arg-str arg-len ) F 0x202 Return the instance-argument 
string for this instance.

Return the instance-argument string that was passed to the current 
instance (when the current instance was created).

Microsoft Word - 1275.DOC [...]

set-args ( arg-str arg-len unit-str unit-len -- ) F 0x23F

Set address and arguments of new device node.

unit-string is a text string representation of a physical address within 
the address space of the parent device. Translate unit-string to the 
equivalent numerical representation by executing the parent instance's 
"decode-unit" method. Set the current instance' s probe-address (i.e., 
the values returned by my-address and my-space) to that numerical 

Copy the string arg-string to instance-specific storage, and arrange for 
my-args to return the address and length of that copy when executed from 
the current instance.

NOTE---set-args is typically used just after new-device. new-device 
creates and selects a new device node, and set-args sets its 
probe-address and arguments. Subsequently, the device node's properties 
and methods are created by interpreting an FCode program with byte-load 
or by interpreting Forth source code.

NOTE---The empty string (any string of zero length) is commonly used as 
the arguments for a new device node, for example: 0 0 " 3,2000" set-args
