[REBOL] Document bug - [catch] There's a catch! Re:
From: lmecir::geocities::com at: 7-Oct-2000 1:47
Hi,
I am sure, I didn't explain the things as they should have been explained.
Here is the example, how the code could look:
Transpose: function [
[catch]
"Transposes Matrices"
Matrix [block!]
] [
Results Width Height Column
] [
throw-on-error [
Results: make block! Width: length? Matrix/1
Height: length? Matrix
repeat Index Width [
Column: make block! Width
foreach Row Matrix [
insert/only tail Column Row/:Index
]
insert/only tail Results Column
]
Results
]
]
Now an example use:
>> transpose [[1 2 3] [a b c] 3]
** Script Error: Cannot use path on integer! value.
** Where: transpose [[1 2 3] [a b c] 3]
Cheers,
Ladislav
