[REBOL] Re: Problems with block of datatype!s
From: ryanc:iesco-dms at: 12-Sep-2001 10:31
Hey Tim,
datatypes seem strange this way. I found the same thing
with 'select some time ago. I eventually somehow figured
out that the trick is to pass the datatype as a word.
I just now noticed that this can be tricky if you need to
convert your datatype, example:
>> to word! string!
** Script Error: Expected one of: word! - not: datatype!
** Where: do-boot
** Near: to word! string!
>>
Ho, ho, ho. Merry feedback. After goofing around for
awhile I came up with this quick fix for you...
>> datatype-to-word: func [dt [datatype!]] [first to-block
join dt "!"]
>> type? probe datatype-to-word string!
string!
== word!
>>
I will send a copy of this to feedback.
