Styles in SO10 in SAP

Hi experts,

I have to use different styles in the single line in so10 text.

Can i know , how to use it .

<B1>&w_inv& &w_vbeln&,,,,,,,,,,&w_head_txt&,,,,,,,,,,&w_copy&</> </>

&w_inv& &w_vbeln& ----left aligned

&w_head_txt& ----Centered

&w_copy& ----right aligned

But, in my case ...based on text , its going to the next line, where i need to print only in single line .

Regards,

Karthik S
