Yeah.  You won't find the word Bozo anywhere in my resume, but it doesn't change the facts.

hehehehe,
now, THAT'S funny ..

Perhaps you mean you are not formally trained. .. I'm not, and few of us are.
QUACK.

I am reading my resume... right now.... just to make sure.....

and also would avoid the re-write of var "text"

I never had changed the value of an argument on my functions.... as far I remember....

Not sure I understand (battling the flu)
But the 'text' var in the subroutine is a local var & has no effect on the 'text' var in the calling routine.
So why would you avoid change the argument?

[LE]

Code: [Select]

(defun rset ( text padding maxlen )
    (substr
        (setq text
            (strcat
                (setaux padding maxlen)
                text
            )
        )                               
        (- (strlen text) (1- maxlen))
    )
)

Here..... get well!

From a purist perspective, which doesn't always seem relevant with Lisp ...

Variable typing and naming is generally considered critical to computer language debugging.

.. but debugging is more than just finding errors after they present themselves, it's also a proactive process to test the flow and integrity of your routine.

One mechanisn for doing this involves the investigation of variable values and testing them against preproven values.

A more consistant strategy for doing this can be determined if the variable values are assigned in more than a seemingly whimsical manner. < sorry, thats my sense of humor taking over>

Yes, but I see your point.

Question for the LISPERS.

No solution .... still ?

How ironic, I was just doing some modifications to my TextInsert Routine & that very thing
bit me in the butt. he he he
Looking back through my older code I sure need to re write most of it.
Who has the time to go back though, until it breaks.
