crashes J. When I respond to the Microsoft error message by pressing the
"Debug"
button, I get something like:
---------------------------
Visual Studio Just-In-Time Debugger

An unhandled win32 exception occurred in j.exe [1640]. Just-In-Time
debugging this exception failed with the following error: No installed
debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time
debugging can be enabled from Tools/Options/Debugging/Just-In-Time.

Check the documentation index for 'Just-in-time debugging, errors' for more
information.

Did you really get APL instead of BPL in the first box??
That would seem even more surprising.

Well, I think "APL" is strangely appropriate.



Yes, appropriate like ERIC from the second example...
Still, odd that different OS produce different results.
In any case, trying your crash producing expressions -

iMg5:~/Desktop jkt$ ja
   require'jmf'
   coinsert 'jmf'
   createjmf 'test1';1e5
   map 'mapped';'test1'
   $mapped
0
   mapped=: 'AAAA';'BBBB';'CCCC';'DDDD'
   $mapped

   3{.mapped

+----+----+----+
   mapped=: 3{.mapped
   mapped

   #&.> mapped

   NB. So, no crash, but strange results indeed...
