Question about displaying strings

[Wes Loewer]

In my example, I wrote

Code:

DIMGROB_P(G1,320,240);        // is this line really necessary?
w:=TEXTOUT_P(str2,G1,0,0);

but the program works the same without the DIMGROB_P() function. Since the text being written to G1 wasn't going to be displayed, is it necessary to use a DIMGROB before writing/drawing something to G1? Is there any danger in writing outside the dimensions? Or are things outside the boundaries safely ignored?
