Öííííííííííííííííí,
3 HP48 G/GX Bug 3
Öíííííííííííííííííííííïíííííííííííííííííïííííííííííííííííííííí,
3 :portnum: { dir ... var } RCL/EVAL fails if portnum >= 2 3

Another G/GX bug has been identified. Thanx to Jeff Healey and
Mohamed Fatri for narrowing the search for me. Here's the scoop.
Suppose you have a directory called AAA which contains a subdirectory
called BBB which in turn contains a variable called CCC. If you store
AAA in a port, you are supposed to be able to recall CCC to the stack
by executing
:portnumber: { AAA BBB CCC } RCL
THIS WORKS FINE on the HP48 S, SX, and G. But it FAILS on the GX if
the portnumber is 2 or higher. In that case, the GX says "RCL Error:
Undefined Name".
Ditto for EVAL in place of RCL.
Ditto if the wildcard portnumber :&: is used, and the object exists
only in port(s) >= 2.
Note: This bug only occurs if the list contains more than one name.
A portnumber-tagged list containing only one name is identical in
operation to a portnumber-tagged name, and works fine in all HP48
models & versions.
This bug may be removed in a future version of the GX. Check your GX
to see if it has this bug.
