Lotus 1-2-3 Macro

I am new to Lotus 1-2-3 Macro. Could any one just explain some simple 1-2-3 Macro to me?

{R}+ n19{R}+n20{R}+n42{R}+n43{R}~
/RV{L}{L}{L}{L}~{L}{L}{L}{L}~
What does these mean? I know /RV is to change formula to value. {R} is to move cursor right and {L} left. But i still can't fully understand the previous codes.
What's the meaning of ~ ?

~ (Tilde) is a 'Return' in Lotus 123 Macros

so the code {L}{L}{L}{L}~{L}{L}{L}{L}~
doesn't make sense, right? after {L 4}~ , execution has returned to Macro, how can {L 4}~ repeat ?

As you say the quote above makes little sense, as such. However if you refer to your first post you will will see the /Range, Values command preceding the four moves Left then the Return to complete the range to convert from formulae to values the next step with in the Values command is to place the converted values hence the other four moves Left and the final Return. This final Return appears to signal the end of the macro and will return control to the user.
It is merely mimicing the Lotus keystrokes .. give it a try /RV etc..
I hope this helps some, if I may suggest this is an Excel forum but there is another for Lotus on this site too .. just a suggestion.
