HP-41 ROM Module wishlist from PPC V9N4P35-36 - Gene - 04-16-2021 08:19 PM Eh, this could have gone into the General Forum, but put it here. The note on the bottom right of the first page of the attached PDF was a wish list for microcoded functions for the PPC ROM II which never materialized. I thought... what if any of these do we still not have ? Item 1: math functions. Check. Those are all in either Sandmath or Extended Stats roms. Item 2: In various ROMs now so check. Item 3: Utility routines --- a) Reverse order catalogs - Nope. Item 4: Extended functions --- a) Store and Recall relative - Don't think so. Item 5: Extended memory functions --- c) POPX - inverse of SAVEX. No ? Item 6: Synthetic programming aids ---- all in various roms. Item 7: Misc. Functions ----- b) and c) Store and Recall a single byte --- ? Of these, POPX is the most interesting to me. Allows use of an extended memory data file as a LIFO stack. SAVEX and the POPX. Does a POPX for that exist ? All the rest of pretty much there or don't generate much excitement from me... except for POPX :-) And it is certainly possible these ARE here and I have forgotten! Oops.

Ohhh.... I like the new Avatar Dan, and am officially jealous. You creative guys have all the tricks. I wonder if id 2CDCC is taken in NY...? RE: HP-41 ROM Module wishlist from PPC V9N4P35-36 - Ángel Martin - 04-17-2021 06:48 AM Not exactly the same as an inverse to GETX, but quite worth looking into: Doug Wilder's POP/PUSH function set use a LIFO file in X-Mem, and are all included in the WARP Module ;-) I added a couple more options and a launcher that groups the different options as follows: PUSH I:A:F:X:Z:T:R <- [SHIFT] -> POP I:A:F:X:Z:T:R with: I: Initialization A: ALPHA F: Flags X: X-Reg Z: Complex value (X & Y) T: Stack {Y,Y,Z,T} R: RTN Stack See attached the relevant pages from the WARP manual with the description. Cheers, ÁM RE: HP-41 ROM Module wishlist from PPC V9N4P35-36 - Ángel Martin - 04-17-2021 07:17 AM Very nice wish-list, especially considering it pre-dates the CX. Here's a few random comments on other entries: 1. Store/Recall Relative.- I like this one, and it's quite easy to implement. But still, wouldn't that be the same as STO IND / RCL IND on the s-Reg location? Thus: STOR = sREG?, X<>Y, STO IND Y; and: RCLR = sREG? , RCL IND X would do the job. 2. COMPILE - in the AMC_OS/X 3. View Program - See CSST in WARP et al. 4. Save/Get Keyboard - See SAVEKA / GETKA in AMC_OS/X 5. MCODE Version of LoadBytes - See LOADB and LOADB+ in the WARP module 6. Reverse CATs - a curious idea but IMHO it's superseded by the XEQ+ concept 7. POPX (again) - not quite the same but in the Equation Solver ROM I added a couple of file pointer functions that facilitate this.: REC+ and REC- move the record pointer by one up and down (and a third function ADVREC moves it by the number of bytes in X).. This: POPX = REC- , GETX But if the goal of said POPX was to use it combined with GETX, wouldn't it be better to use a PUSHX that saves the X-value but doesn't move the file record pointer instead? Ruminating in the background... ;-) RE: HP-41 ROM Module wishlist from PPC V9N4P35-36 - Ángel Martin - 04-18-2021 06:38 AM FWIW, here's the code for STOR and RCLR in case you're interested: Code: 092 "R" |
