I downloaded from hpcalc.org Gjermund Skailand's intpol23 library. Two
programs in it (LS2 and LS3) show error "XLIB 688 49 error: undefined
Xlib name" in 48S, while they work on 48SX. Readme file says "The
HP48' version was compiled with rom version HP48-R", while my 48S is
ROM version J.
Could I convert the library to work on 48s calculator? "intpol4823.s"
code was provided in zip file.
I'm an absolute newbye in 48's programming.
Please help me, thanks

I think maybe the intpol library uses matrix functions which were not
available in the 48SX, most probably the LSQ which do the least square
solving. However, if you search hpcalc.org I am quite sure you should be
able so find other programs which fit data to second and third order
polynoms by least square.
