POV Code using Gosub

[Andres Rodriguez]

Some time ago I saw code posted in the forum using Gosub to spell PICAXE on a wand. I have searched every way I could imagine (wand, POV, Persistance, etc.) and no luck. I would appreciate it if anyone knows where it is and would share the information.
I have a working prototype but it is very cumbersome to change the message.

Something like the axe035 spacewriter kit? The code there says how to write PICAXE using gosubs.

I'm currently making one too - only my one has a real time clock, DS18B20, and 20 RGB LEDs.

Is this the thread you are looking for?

Actually, I had only seen the one mentioned by Andrew but I am glad you pointed at this one as well.
Thank you

Have a look at ON GOSUB too......

eeprom 0,("PICAXE")

symbol loop1 = b0
symbol char  = b1

for loop1 = 0 to 5
    read loop1,char
    select case char
        case 65 to 90
            Char = Char - 65
            on Char gosub A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z
    end select		
next

Note: Some labels will have to be changed as these are reserved words.

ON-GOSUB can be a bit of a memory hog but you can usually translate an ON-GOSUB to a GOSUB and ON-GOTO ...

for loop1 = 0 to 5
    read loop1,char
    select case char
        case 65 to 90
            Char = Char - 65
            [b]Gosub ShowChar[/b]
    end select		
 next
End

ShowChar:
  on Char [b]goto[/b] A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z

Good point !!!, but in these days of huge memory sizes and multi slot monsters who's counting
