Operating Systems OS X (Apple) An Audio Function Generator... Post 302970209 by wisecracker on Monday 4th of April 2016 01:36:59 AM

Hi Don...

# defined, $VER will not be expanded in an awk string constant.

This made me smile...

It is not meant to be a variable at all.

As I am still an ancient AMIGA _fanatic_ this is how any executable file in the AMIGA directory tree displays what the program and its version is when _asked_.
$VER is always the first 4 characters followed by a space and after that is pure text. I use underscores instead of other spaces.
So if you see anything of mine it will always have $VER in it. In AudioScope the '$' is escaped so as not to be confused with a variable in 'sh'...
It is a quirk of mine...

All of the files are now created but I forgot about the 'close()' you mentioned in post 8, my bad.

Anyhow it looks as though this creation will be yours too... ;oD

Once again you have added to my learning and I had thought about a function but was not sure at this stage where to start.

As for the ARBITRARY waveform size anything greater that 480,000 bytes is OK and that was my next job...

2 questions:-

Eventually for the ARBITRARY generation I was going to call the shell command ed as this is difinitve on all versions of Linux and UNIX flavours.

1) Which editor would you use to call?
2) Is it possible to save the file without a newline?

I have checked three editors, 'Gedit' is my GUI editor of choice, 'ed' and 'vi(m)'. I might be missing something with 'ed' and 'vi(m)' as I am no expert by any stretch of the imagination...

TIA.
