I've got my prototype Hz# function working. Done with BASIC statements/functions with some macro help from TiddlyWiki.
A "Musical Notes Dictionary <https://basicanywheremachine.neocities.org/sample_programs/Musical%20Notes%20Dictionary.html>" tiddler to store the name-value pairs of NoteNameAndOctave and frequency. The "Hz#(note$) <https://basicanywheremachine.neocities.org/sample_programs/Hz_setup.png>" tiddler that defines the Hz# function. - the quickest no-fuss-no-muss approach involves putting in browser local storage all of the name-value pairs of musical notes, and getting the Hz# function to take the note$ parameter and look it up in browser local storage - the list of SetLocalStorage() statements is generated by TiddlyWiki at program run time For any program in which I want to use Hz#, I add an "include" macro call at the top of the program: <<include "Hz#(note$)">> Sample program: Amazing Grace *(crude first attempt)* - view the source code before run-time TiddlyWiki processing <https://basicanywheremachine.neocities.org/sample_programs/Amazing%20Grace.preinclude.bas.html> - view the source code at run-time <https://basicanywheremachine.neocities.org/sample_programs/Amazing%20Grace.bas.html> *(i.e. the "wikified" source code)* - run the program <https://basicanywheremachine.neocities.org/sample_programs/Amazing%20Grace.run.html> On Monday, August 15, 2022 at 10:17:52 PM UTC-3 Charlie Veniot wrote: > In BASIC Anywhere Machine, the SOUND statement is used to play sound > frequencies for a specified length of time. > > Syntax: SOUND *frequency*, *duration* > > Typing in frequencies for specific musical notes is a pain. > > Intead of typing in frequency numbers for every note, it would be nice to > be able to just type in the note (i.e. note name and octave.)
