a question about sapscript on auto wrap

Hello, everybody.

Today, I meet a problem about sapscript.

I list it as following, hope can get reply from you.

I'm developing a form using SAP script(not using smartform, it's due to the customer's requirement)

and the trouble is when I write a long text to screen, it is too long more than the page size. So can I set a maxlength for it, make it auto wrap, if it exceed the max length, make it written begin from next line.

Is it possible? And if not a long text, but a unline, is it possible too?

In brief, how to realize the auto wrap in sapscript?

Any suggestion and reply is welcome.

thank you very much
