Length limit attribute?

R2005 Vlisp:

This might sound dumb, but is there a way to set a limit on an attribute so that after a certain number characters are typed in at the prompt, the prompt will close and the next prompt will appear?

Thanks

Probably VBA would be a better bet. It will check the length of the string
within a text box.

so that after a certain number characters are typed in at the prompt, the
prompt will close and the next prompt will appear?

 

BillZ,

That sounds like controlling the input stream. I think you would have to
use (grread) and convert the ascii codes to characters then echo them to the
screen so the user can see what he's typing all the while creating a string
variable that represents the user input. When the string reaches a certain
length you (princ "\n") and continue? I did something similar when I
created my own grread prompt myself. But it was made to use the combo of
keyboard and mouse input.

Thanks,
I may let this idea go as it could be problematic knowing the exact number of characters in the line.

Yes, I agree, the input stream functions are a little low level for Autolisp
to handle. System to system the font and screen size changes so who knows
what the length of the line is accept a real low level function, but
typically there just isn't enough support in lisp to perform low level
operations.
