Silly question about print()

[dpann]

Hello all,
I am using uLCD_gen4-24DT (Diablo 16) and ViSi and I jsut start to learn this product.
My problem is about the print() function :

txt_FontID(FONT_4) ;
txt_Width(2);
txt_Height(2);
txt_FGcolour(BLUE) ;
txt_BGcolour(BLACK) ;
gfx_MoveTo(10 , 78) ;
print(1234) ;
Until there it's OK

Later, I want to replace the first text with another text at the same place :
gfx_MoveTo(10 , 78) ;
print(5678) ;

The result is the two texts are mixed and not readable. Therefore, how to erase the first text before printing the second one ?
Thanks for your help

Hello,

Welcome to the forum,

You can use the command,

txt_Opacity(OPAQUE);

to print the text with a background. It will be set to TRANSPARENT initially which is why you see the text being drawn on top of each other.

I hope this helps

Best regards

Paul
