Members of the forum -
I defined an adverb to apply a test to a bunch of files but I made a thinko
and wrote it as though "fread" returns a number in non-error cases:
doOnFiles=: 1 : 0
assert. 0<:rc=. fread y
u rc
)
Of course, I meant to do a check like this:
assert. -._1-:rc=. fread y
Anyway, the mistaken version showed a disturbing tendency to end my
"jee.exe" session when using the debugger:
doOnFiles=: 1 : 0
assert. 0<:rc=. fread y
u rc
)
$flnms=. {."1 dir 'DPLoan???.psv'
145
rc=. ([:','&e.]) doOnFiles&>flnms
|domain error
| 0 <:rc=.fread y
NB. Turn on debugger and re-run:
13!:0]1
rc=. ([:','&e.]) doOnFiles&>flnms
|domain error: doOnFiles
| 0 <:rc=.fread y
|doOnFiles[0]
y
DPloan000.psv
$rc
28999463
NB. OK - I see the problem, so turn off halt mode:
13!:0]0

I was thrown out of J back to the DOS prompt.
Anyone else see behavior like this? The same thing happens with a "j.exe"
session as well. I'm running J6.02 under Windows XP, SP2.
Thanks,
Devon
