Because debug'' rolls easily through my fingers, I assign
debug=: [: ([ 13!:0) [: ". 'DEBUG=:-.DEBUG'"_
DEBUG=:0
This turns debugging on but no longer drops the session back to prior
level, and I'm *certain* it, or a similar verb did so in early 9.01
releases. Here's an example continuing session, either my expectation or j
is incorrect here.
foops=: 3 :'~y'
debug''
1
foops'y here'
|syntax error: foops
| ~y
|foops[0]
DEBUG
1
y
y here
debug'' NB. expect 13!:0]0 effect
0
y NB. didn't get it.
y here
13!:0[0
y
|value error: y
DEBUG
0
Explanation appreciated, Dave
