String question

BTX

Hi.
I'm getting crazy with this simple problem.

This works fine.

··· tv.str(string($0C,3,"It's finishing................. ",13))··········································· '····

Thanks Phil.
But in Scott example ...he want o show a dec in the same way that a string...I want to replace a full string expression, with a new one form, that let me to send to TV a directly formated string (carrieage returm plus colors, in a simple form like Doing("xxxxx")).
Which is the base problem to pass a string variable, as string in the TV object?

Regards.
Alberto.

It's the same issue: you can't use a variable in the string function, since the string is "built" at compile time. However, you can make a separate call to tv.str with just your variable as an argument. (I assume your variable contains the address of a zero-terminated string.)

TV_text is being used. How does one display the ASCII of a received byte?___

It seems to provide display of string, dec, hex, bin. Am I not using the proper object to display characters?___

Harley,

Use the out function. It will display a single character as ASCII.

Sorry Phil... I'm trying to pass my variable as argument, it's not clear for me, how ??
Separate call....is not my Doing() ??
If I can't put a variable into the string command, how to pass my variable value to it ??
I insist because, I think i could get the same problem in the future, when I'll try to use an existing object.
Could you brieftly, write for me a couple of code, to show me what you want to say ?

Thanks again...
Alberto.

Hi alberto,

Sure. Try this:

PUB Ftest
    tv.start(12)
    Doing("A")
    Doing("B")

PRI Doing(texto)
    tv.str(string($0C,3))
    tv.[b]out[/b](text0)
    tv.out(13)                                 
 

If you were using strings instead of single characters, you'd do something like this:

PUB Ftest
    tv.start(12)
    Doing(string("It's doing A."))
    Doing(string("It's doing B."))

PRI Doing(texto)
    tv.str(string($0C,3))
    tv.[b]str[/b](text0)
    tv.out(13)                                 
 

Also, notice that I moved the call to start so it would only be executed once.

Oh !! thanks so much Phil for your help.

Now I understand, what you want to say, and it's working fine...
It' very clear, tv.str accept the variable 'texto', but without the command 'string', then you put it after the Doing, if you want to show more than one character.

I think I'm getting a bit older........too much Java, C++, VB, VFP, MASM, etc.etc. no more RAM available in my mind perhaps.

Alberto.
