GCL returns obscure error message:
------------------------
MAXIMA> (describe 'displa)
DISPLA - internal symbol in MAXIMA package
property TRANSLATED:
T
property MACSYMA-MODULE:
(RUNTIME)
-----------------------------------------------------------------------------
DISPLA
[Function]
(not found "dir")
Maxima encountered a Lisp error:
Error in PCL::PCL-DESCRIBE [or a callee]: Cannot open the file NIL.
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
MAXIMA> (describe 'dir)
DIR - internal symbol in MAXIMA package(not found "dir")
Maxima encountered a Lisp error:
Error in EVAL [or a callee]: Cannot open the file NIL.
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
--------------------------------------------
Is this a feature of GCL , or a lack of code documentation?
