Hi Gregg, Abdel
from my experience with Rebol dll interface you should also try put into the
structure deffinition 41 val [char!] instead of the string! or char* like:
loc-data: make struct! [
name1 [char!]
name2 [char!]
name3 [char!]
.....
......
name40 [char!]
name41 [char!]
lat [decimal!]
lon [decimal!]
....
]
but maybe this annoying thing was improved in the new beta release of View?
anyway, here is simple function for easy generation of such structures I
used some time ago:
gen-chars: func [word-name num /local result][
result: copy ""
insert result newline
repeat n num [append result join word-name [n " [char!]" newline]]
load result
]
example:
GFL_COLORMAP: make struct! compose/deep [
(gen-chars "Red" 256)
(gen-chars "Green" 256)
(gen-chars "Blue" 256)
] none
good luck!
regards,
Cyphre
