HP41: how to use "Solve" from Math module in another programm?
Hello,
the program below prompt 3 times in "SOLVE". How to make it working automatic = no prompt but it would take the data from ALPHA and X automatically? Any advice is welcome. LBL "IGAM00" XEQ "SOLVE" "ZWFF" 0.000000001 1.461632144 RTN LBL "ZWFF" XEQ "GAMMA" 2.5  RTN END HP71 4TH/ASM & Multimod, HP41CV/X & Nov64d, PILBOX, HPIL 821.62A & 64A & 66A, Deb11 64bPC & PI2 3 4 w/ ILPER, VIDEO80, V41 & EMU71, DM41X, HP75D

Hey Floppy,
Did you check out Appendix B for calling "SOL" as a sub? Page 59. B

The reverse gamma "IGAM00" works "a bit": takes much of time. I will have to find a better one. (reverse gamma "IGAM00" is for the area positive x between 0.0001 and the minimum at approx 1.461) Quote:LBL "IGAM00" in other area for example for x> 1.461 (see from page 27) there are more precise approximations https://ir.lib.uwo.ca/cgi/viewcontent.cg...ontext=etd HP71 4TH/ASM & Multimod, HP41CV/X & Nov64d, PILBOX, HPIL 821.62A & 64A & 66A, Deb11 64bPC & PI2 3 4 w/ ILPER, VIDEO80, V41 & EMU71, DM41X, HP75D

There's an inverse Gamma function in the SandMath module; it may be interesting to check as well.
Look for "SM44" in here. Page #106 in the manual describes the implementation. "To live or die by your own sword one must first learn to wield it aptly."

I updated my previous post which was indicating inverse instead of reverse. And added a link explaining some research in reverse gamma. The program in this threads needs 4.40min on V41R9F for finding 0.5 when we make 1.77245 XEQ "IGAM00".

Thanks.
Issue: "V41 R9F" says "Nonexistent" (module SandMath uploaded). Looks like IGMMA is not in. SandMath44 is probably in the ZIP of the CL data internet page. Will look now at this. ROM files are in a Zip. No *SM44.mod for "V41R9F". I have to further search where it could be (advices welcome). Remark: I am not so expert to program now my Nov64d with SMAT44.ROM from the CL homepage ZIP. Will come the next days/weeks. For now, I would preferably test all on the "V41 R9F".

Attached is a ZIP file with the SandMath44 and Library#4 MODS  you can plug them on V41.

Thanks.
By uploading both MOD files from the ZIP attachment (see previous post), the first try in "V41 R9F" was positive. Further tries not. We have to stay in touch. By using "IGMMA" from Sandmath44 the calculation time is coming down to few seconds (not several minutes like "RGAM00" with "SOL" Math module; however the "SOLVE" from Advantage" is much better and my recommendation is to use it instead of "SOL" from math module).
