WOW
Probably simple to you guys but I think the two parsing solutions are really brilliant. I don't know TStringlist or TStrings that well, just learning really, but I'm finally beginning to understand and appreciate the two solutions.
Thanks

I guess what i do there is not what you was searching for, or?
This will generate an array of lines which not exceed a given limit (80 chars by default)
Afterwards you can easy iterate over like ... ->
Code: Pascal
[Select]
[+]
[-]
var
sa
:
TStringArray
;
i
:
Integer
;
begin
sa
:
=
PrepareLines
(
'Header: xx bbb ccccc dddd eeee fffff gggg kk i jjjjj kkkk lll mmmm nnn ooo ppppp qqqqq rrrr ssssss tttttt uu vvv www xxx yy zzz.'
,
10
)
;
for
i
:
=
Low
(
sa
)
to
High
(
sa
)
do
Memo1
.
Lines
.
Add
(
sa
[
i
]
)
;
