Bob is right - LiveCode does not natively know how to handle lines of data as a
set of fixed-length fields, so you have to roll your own field defs and apply
them to each line.
Here is one way:
local sFieldLengths = "5,16,1,3,8,8"
on mouseUp
answer file "Select a text file with fixed-length fields:"
if it = empty then exit to top
put url ("file:" & it) into tData
split tData with CR
repeat for each key tLineNum in tData
put mySplit(tData[tLineNum]) into tData[tLineNum]
end repeat
-- now 'tData' is a two-dimension array
-- of fields by number within lines by number
end mouseUp
function mySplit pRecord
put 0 into tOffset
put 0 into x
repeat for each item tLength in sFieldLengths
add 1 to x
put char (tOffset+1) to (tOffset+tLength) of pRecord into tFieldArray[x]
add tLength to tOffset
end repeat
return tFieldArray
end mySplit
But if you have control over the data format and can use tab-delimited data, it
becomes much simpler:
on mouseUp
answer file "Select a tab-delimited text file:"
if it = empty then exit to top
put url ("file:" & it) into tData
split tData with CR
repeat for each key tLineNum in tData
split tData[tLineNum] with tab
end repeat
-- now 'tData' is a two-dimension array
-- of fields by number within lines by number
end mouseUp
Food for thought...

Hi,
Is posible in LiveCode delimite the chars of a variable inside of one array
to assign other variable that assign the values into the array to each
element.
Example, so my explanation is confused :) I know.
I have a string with:
00000Description nameT001 0.00 0.00
and I need to asign the entire string to the array but autofilling the
values like in Pascal when use "Type of"
So the string will be... splited by the definition of the array, but I don't
know if is posible define one array with the length of her elements.
00000
Description name
T
001
0.00
0.00
Salut,
Josep
