Just to reiterate, that this works in 4D v11 but not in A4D v5.0r17.
Further to my previous emails I have since discovered that if I put the CR & LF
in a variable first, Position and Replace String happily work!
$Text:="one"+char(13)+char(10)+"two"+char(13)+char(10)+"three"$test:=char(13)+char(10)
$test:=char(13)+char(10)
$pos:=position($test;$Text)
$text:=replace string($Text;$test;"CRLF")
WRITE TO CONSOLE("test,6: = "+$Text)
Result in the console is:
test,6: = oneCRLFtwoCRLFthree
This doesn't work if I just put the CR in the variable ($test:=char(13))
cheers
