Using variables in SOUND command
« Thread started on: May 14th, 2010, 6:11pm » |

hi,
I've got an actual BBC master, but I can't believe the language is much different!..
Anyway, I'm trying to build a program which allows me to manipulate the SOUND and ENVELOPE parameters individually, and save presets.. that kind of thing. But I noticed I need to also send &11 and &1010 to the channel parameter, along with other non-numeric values, which can't be done with the single C numeric variable I'm using.
So, I change the C value to C$, but now the SOUND command complains of a 'Type Mismatch'. eg SOUND C$,1,100,200.
How to I program my way around this?
Many thanks

Why not? You could define a number of constants such as:
Code: channel = 1
flush = &10
hold = &1000
then you can build your variable C by combining them as required:
Code: C = channel + flush + hold
SOUND C,1,100,200

Using a string variable seems unnecessarily complicated to me, but if that's the way you want to do it you can convert the string to a numeric using EVAL:
Code: C$ = "&1011"
C = EVAL(C$)
SOUND C,1,100,200

Hi Richard,
Thanks for your reply - I went wrong thinking that a string variable was required for anything but numerical values (including the ampersand); I'll now be able to finish what I started!
Cheers
