Hi all !
I tried the exception handling. It works sometimes. It does not always
work? J can not give errors because the exception handling does not
always work? There is no way to fix it so we have to accept random
results of our programs instead of errors?
p=: 3 1 0 2
q=: 3 1 1 0
A=: A. :: (!@#)
A p
20
A q
24
A. q
|index error
| A.q
a=: 3 : 0
try.
A. y
catch.
'error'
end.
)
a q
error
Cheers,
Erling

Sure, and, for example:
typetrap=:4 :0
try.
x/y
catch.
'this is a trap'
end.

1 typetrap 1
this is a trap
Or, if you want some other kind of result (or if you want to see valid
arguments):
+`'' typetrap i.4
6
No problem, right?
Thanks,
