Old 8-bit computer command ideas in a console program

Short version: Trying to replicate three old 8-bit computer commands in a console program running on a Mac, so I can't cheat with DLLs, but maybe some kind of Mac magic behind the curtains?
1) BEEP. I accidentally found the command NSBeep_() in some source code on a forum message. It works, but I can't find any documentation on it anywhere. Also, I suspect there are number of other commands with the underscore "{Command}_()" syntax. How can I learn more about these?
2) CLEAR - Clear all numeric variables to 0 and all strings to "". Admittedly, this is kind of crazy, but...um...reasons!
3) SCREEN$ - Capture the console display and save as image.
4) SOUND - Generate specific frequency and wavelength tones without loading an mp3/ogg/Flac sound file.
Any help would be greatly appreciated.

Define all variables, both numeric and string, within a structure. Use ResetStructure() to reset all as at first (numeric = 0, strings = "" or more accurately null).
Code: Select all
Structure all_vars
; change the names and typed to match your needs
n1.i
n2.i
n3.b
s1.s
s2.s
; and so on
EndStructure
Define vars.all_vars
vars\n3 = 5
vars\s2 = " blah "
Debug vars\n3
Debug vars\s2
ResetStructure(@vars, all_vars)
Debug vars\n3
Debug vars\s2

Very cool. I have no experience with the Structure command, so I'm looking forward to learning more about it. Thanks!

Seems you refer to
windows API calls.
The
MSDN has all the information for those (
Beep). Check
Section 5.3 of the
PureBasic Survival Guide

Running on a Mac, so not sure that's gonna work.
Thanks all the same, though!
