Status on partition problem

[Programmingkid]

I have tracked down some issues with the file mac-files.c. The one big issue is with a variable called str. It isn't set properly. When I type this command "dir cd:9,\Utilities", str should be set to "9,\Utilities". argstr should then be set to "\Utilities". This does not happen. Instead str is set to "9".

I traced the issue with a function called my_args_copy(). That led me to a forth word called my-args. I'm not sure what this word does, or where it is defined.

Reading some of the comments in various files, someone thinks that if no partition is specified, it means the whole disk is selected. My plan is to change this so that is no partition is selected, it means to select the first Apple_HFS or Apple_HSFX partition. If someone wants to use an entire disk, they have to explicitly specify it by using zero as the partition number. This fix should make automatically selecting a partition work.

Hope this makes sense.

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 
representation.

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
