Hi, when I use the fontsize command in the mask

text(5,10, 'Gain','FontSize',10)

I get the warning:

I can change the font if I use|:

text(0.5,0.7,'\bf\fontsize{10}text sample')

but if I have a defined string, e.g.

select = 'version a';
str = sprintf('Selection = %s', select);

then, to display the string on the mask, I can use

dips(str)

or

text(5,10,str)

but in both cases I don't know how to change the font size.

You may not realize, text() used in Simulink Mask doesnot have full functionality as in MATLAB. See this note in the doc.

While this text function is identical in name to its corresponding MATLAB® function, it provides only the functionality described on this page.

To solve your problem, you need to construct a string from your variable and the TeX formatting and then use text(x,y,'text')
