[pdp-discuss] 'Operation: delete not defined for type: (void)' error

[Richard Jones]

I've written one of those handy ctrl scripts that is used so much in
the book examples.  It's giving me some odd problems.   The entire
.css file is shown below.  When I try to autorun it, the program
crashes with the following error:

     bp++> Operation: delete not defined for type: (void)
     ./Tester_Ctrl.css
     >0
     PDP++ saving recover file(s) and exiting from signal:
segmentation violation
     Segmentation fault


If I load the same file at the css prompt, however:

     bp++>load "/Tester_Ctrl.css"

and then do:

     bp++>EditObj(tester_ctrl)

it works fine.  No 'delete not defined' error, no core dump.
Interestingly, if I've comment out the next-to-last line in the css
file that instantiates the tester_ctrl instance, do the load at the
prompt, and then do:

     bp++>Tester_Ctrl tester_ctrl;

I get the dump and error.   What is the error telling me and what
should I do about it?

Many thanks.
