AddApp bug?

It seems to me that
*AddApp osvar:!app
does nothing, yet
*AddApp <osvar$path>!app
works fine, and the app appears in Resources Apps..

Is this what others see – and should both work?

I did have a look at the source in BootCmds.c.main, and it seems to set dir_name to “@” (CSD?) if there is no dot in the parameter, before before canonicalising it. Which confused me, as there is no dot in either!

I’m fairly certain <osvar$path> will be expanded by OS_CLI (because it’s very obviously a system variable), whereas osvar: will be ignored (FileSwitch will expand it when it canonicalises the filename AddApp provides).

But yes, AddApp’s behaviour does seem a bit fishy
