I think there is a :while :endwhile too
thoses are really missing (to my point of view).
1. those things are probably not very hard to implement. However:
2. I try to minimize non-standard extensions of GNU APL because every such extension
creates incompatibilities of APL programs that are using them. My idea of free software
is that not only GNU APL itself should be free but also APL programs running on GNU APL.
And for a free APL program to be useful it is important that is is portable between different APL interpreters.
