Sea stack
Hi,

Sometimes it is convenient to see what it is into stack, when no printer, to better programing.

Here is a little routine that I use always on my HP41, with WP34s, I use Printer virtual.

From PPC and HP41 examples book.

Wink Gérard.

Gérard.

The 34s has a SHOW command (g EXIT).
Try it (use the up and down arrows) and see what you get. ;-)

RE: Sea stack
Bonjour Gérard,
Merci pour ce petit programme.
J'aime particulièrement la ligne 18 qui permet au programme d'être très compact.
Cordialement,
Sylvain

Hello Gérard,
Thanks for this small program.
By removing the unnecessary RDN or RUP in the main body, step 18 make it very compact
Best regards,
Sylvain

RE: Sea stack
Loop-unrolling saves 3 bytes but makes it 2 lines longer:

Code:
 01 LBL "STKDISP"
 02 "L="
 03 ARCL L
 04 AVIEW
 05 PSE
 06 "X="
 07 ARCL X
 08 AVIEW
 09 PSE
 10 "Y="
 11 ARCL Y
 12 AVIEW
 13 PSE
 14 "Z="
 15 ARCL Z
 16 AVIEW
 17 PSE
 18 "T="
 19 ARCL T
 20 AVIEW
 21 END

Kind regards
Thomas

Hello Thomas,
Actually, it is 4 bytes shorter and effectively 2 lines longer.
Kind regards,

That's because I counted the bytes before removing the final PSE instruction. Thanks for the correction.

Cheers

Optimized? Here comes the definitely optimized version for the '41:

Code:
01 7PRSTK
02 VIEW L
03 END

OK, this requires a card reader... ;-)

When you got too many it is difficult to track everything.

RE: Sea stack
Salut Gérard,

Je pense qu'il y a un problème de compréhensions entre vous et Massimo.

Voici ma compréhension de vos échanges ...

Vous: vous avez deux lecteurs de carte magnétique.
Massimo: moi, je ne me souviens plus de comment j'en possède.
Vous: Comment pouvez-vous ne pas vous souvenir de la quantité que vous avez ?
Vous: Je n'ai probablement pas compris votre intervention.
Vous: Normalement on devrait se souvenir de ce qu'on possède.
Massimo: Lorsque tu en possèdes beaucoup, il arrive d'en perdre le décompte.

Je ne pense pas que Massimo n'a été en aucun moment agressif dans ces échanges.

Cordialement,

Sylvain

RE: Sea stack
Thanks Sylvain, and sorry Gérard: I didn't mean to sound offensive nor aggressive.
Actually I, sometimes, find difficult to fully understand what you mean. My fault, of course.

Massimo
