Comments in RPL? - John R. Graham - 09-08-2014 06:14 PM
Is there a comment delimiter defined for RPL so that comments can be embedded when editing on the PC?

I believe the @ symbol is will serve the purpose:
<<
@ this is a comment line
DUP DROP
>>
On the calculator, the comments will be removed, if I recall correctly.

Hi,
On my HP-28S, I use to copy my programs in a paper notebook.
Comments are easy to insert as well as a description of the arguments to use and in which order to put them in the stack.
On the calculator, program readability is poor on the HP-28S screen.
But if I may have to insert comment directly into a program, I will use a string followed by a DROP command.
For example:
Code:
« "* INPUT 1: n natural number to be tested" DROP
DUP 0 "Initialize MAX & TOF " DROP
WHILE
ROT DUP 1 > "Loop until last term " DROP
REPEAT
IF 2 / DUP FP "Compute next term of seq. " DROP
THEN 6 * 1 + END "Even:Half Odd: Triple + 1" DROP
ROT OVER MAX "Reset MAX value " DROP
ROT 1 + "Increment TOF " DROP
END
DROP "Remove last term of seq. " DROP
"** OUTPUT 2: MAX altitude 1: Time Of Flight" DROP

Clever!
Thanks
