Some time ago somebody posted something about finding the URD or CSD from the
fileswitch system variables under RiscOS 3.1.  It was something like:-

<FileSwitch$<FileSwitch$CurrentFilingSystem>$URD>

Now if you try to use this to set another system variable to the root path,
with a command such as:-

set r <FileSwitch$CurrentFilingSystem>:<FileSwitch$<FileSwitch$CurrentFilingSystem>$URD>

you get

ADFS:$URD>

as GSTrans is not interpreting the nested angle brackets correctly.

The only solution I can come up with is:-

set r FileSwitch$<FileSwitch$CurrentFilingSystem>$URD
seteval r <r>
set r <FileSwitch$CurrentFilingSystem>:<r>

Is there a better way?

Jon.

I assume you could use Owen Smith's suggestion of OS_FSControl 37
(canonicalise name) on "$" for this.  If you want to do it all in CLI
commands then your solution is probably as good as my:

Set FS <FileSwitch$CurrentFilingSystem>
SetEval CSD "<FS>:"+FileSwitch$<FS>$CSD

(or replace CSD with URD) though, as I said, the first line is not
necessary so you could do it in one (long) command.
