This is a TI‐89
implementation of N3GO Gary O’Neil’s J‐pole
If you own an Android device, there’s an excellent Texas Instruments
calculator emulator called Graph 89
that emulates a TI‐89 among several other graphing calculator models.
I’ve actually been using Graph 89 when writing this program.

- • Removed the myinput() subprogram; the slowness of the loops in it
caused annoying delays, and the numeric input handling when using plain
Input() is good enough. Less is more.
- • So the TI‐89 does support arrays (“lists”) after all... now using
a list for the prompt in myinput().
- • Now using a .89g file, with its contents being placed in a ‘jpole’
folder, rather than a .89p file.
- • New subprogram myinput() that checks the validity of user
- • Minor changes.
- • tuning(), velocity(): Added some pauses in the output.

- • velocity(): Improved the display of frequencies.
- • Slight tidying up.
