Re: [Bug-apl] )IN crashes

[Juergen Sauermann]

Hi David,

thanks for isolating the fault. I fixed it in SVN 327.

The fault was created by native functions being )OUT-ed and )IN-ed.
They are now handled properly, but the file created by )OUT is no longer
suitable as workspace exchange file when it contains native functions
(because native functions are a GNU APL extension that will not be 
understood
by other APL interpreters).

)OUT issues a warning for every native function being written.
