There are a few ways to do this. One is to use the pos() or index() functions
within a substr() function to split out the individual lines. You will find it
easiest to assign the hex string to a variable, especially if the newline or CR
is part of another string. The other way I can think of is to use a translate()
function. Translate() allows you to translate more than one thing at a time, so
you can translate all spaces to some unused character, and at the same time,
translate all newlines or CRs to spaces. You can then split the lines on a word
basis, and translate the special characters back to spaces.
