Programming Question!!! Message #1 Posted by Harrington on 13 June 2004, 1:38 p.m. Ok this is what I have so far : <<" enter function""" input obj->-> a <<a partfract "y(x)"->tag->str MSGBox>> now I'm getting what I expect to see from the above what I really want to do is Dtag y(x) into another function (Intergration function) in function to excutes the solution to y(x) by intergrating it . I know it is holding what ever the anwere is, for input (a) in stack. have any ideas?

Re: Programming Question!!! Message #2 Posted by James M. Prange on 14 June 2004, 2:23 a.m., in response to message #1 by Harrington Well, yes, my idea is that it would be a lot easier to help you if you were careful to post exactly what you're trying to do. In particular, pay very close attention to capitalization, spelling, and spacing, both on your calculator and when posting online. I suggest that you use a Conn4x "Text" file transfer or "Edit as Text", then copy and paste it into the post, and (for this forum) enclose it between [pre] and [/pre] "BBCode" tags. Doesn't: %%HP: T(3)A(R)F(.); \<< " enter function" "" INPUT OBJ\-> \-> a \<< a PARTFRAC "y(x)" \->TAG \->STR MSGBOX \>> \>> seem a lot better than: Quote: <<" enter function""" input obj->-> a <<a partfract "y(x)"->tag->str MSGBox>> Also, note that if you use the copy and paste method, I can just download your code to my calculator and try it out, rather than trying to key it in, correcting errors at the same time. Regards, James

Re: Programming Question!!! Message #3 Posted by harrington r on 14 June 2004, 2:38 a.m., in response to message #1 by Harrington oka thanks for the idea: my question was is it possible to excutues partfrac and call the solution into intergration in the same program . which the syntax yet has not been written.

Re: Programming Question!!! Message #4 Posted by James M. Prange on 14 June 2004, 3:02 a.m., in response to message #3 by harrington r Do you mean that you want to use the result from PARTFRAC for something else in the program? Why not just DUP it and leave that copy on the stack for later use? Like this: %%HP: T(3)A(R)F(.); \<< " enter function" "" INPUT OBJ\-> \-> a \<< a PARTFRAC DUP "y(x)" \->TAG \->STR MSGBOX \>> \>> Regards. James

Re: Programming Question!!! Message #5 Posted by Harrington on 14 June 2004, 5:11 p.m., in response to message #4 by James M. Prange yes but I inten to implement another built in function integrate to slove the residues from the Partfrac get it

Galling and appalling!!! Message #6 Posted by Karl Schneider on 15 June 2004, 12:18 a.m., in response to message #5 by Harrington "Harrington" -- An excerpt from James Prange's reply to your first post: Quote: Well, yes, my idea is that it would be a lot easier to help you if you were careful to post exactly what you're trying to do. In particular, pay very close attention to capitalization, spelling, and spacing, both on your calculator and when posting online. Your three posts, verbatim: Quote: Ok this is what I have so far : <<" enter function""" input obj->-> a <<a partfract "y(x)"->tag->str MSGBox>> now I'm getting what I expect to see from the above what I really want to do is Dtag y(x) into another function (Intergration function) in function to excutes the solution to y(x) by intergrating it .

I own the 28C, 48G, and 49G, but freely admit that I don't know RPL well enough to help (nor do I desire to become more proficient). If I were James, though, I wouldn't take the time to provide further counsel. I just don't think you "get it". -- Karl S.

Re: Programming Question!!! Message #7 Posted by James M. Prange on 15 June 2004, 4:02 a.m., in response to message #5 by Harrington No, I'm not at all sure that I "get it". By "Partfrac", do you mean that your program is named "Partfrac"? If you really mean "PARTFRAC", then write it that way. Please do make an effort to write standard English. Try to write not only in a manner that can be understood, but in a manner that can't be misunderstood. Doesn't having the result from PARTFRAC on the stack help? You can use that result as the argument for something else that could follow what you have so far. For what you're doing, it seems to me that it may be better to have the INPUT command force the Algebraic/Program-entry mode and start an algebraic object, and you may as well have it check the syntax of the algebraic object too. So how about: %%HP: T(3)A(R)F(.); @ Results from BYTES: @ # B716h @ 104.5 \<< " enter function" { "''" 2. ALG V } INPUT OBJ\-> \-> a \<< a PARTFRAC DUP "y(x)" \->TAG \->STR MSGBOX \>> \>> Also, there's no need to use a local variable structure for this program. The above program takes an object from the stack, stores it to a local variable, and then puts the contents of the local variable back on the stack and uses it for the argument to PARTFRAC, and finally removes the local variable when it's done. Why jump through so many hoops? Maybe try: %%HP: T(3)A(R)F(.); @ Results from BYTES: @ # 78EEh @ 88. \<< " enter function" { "''" 2. ALG V } INPUT OBJ\-> PARTFRAC DUP "y(x)" \->TAG \->STR MSGBOX \>> That's smaller and faster, and ends up accomplishing the same thing. Regards, James
