Help with SAPscript for printing checks

I'm developing a SAPscript to print checks. I've run into two problems which I've listed below:

1.) I'm print the check amount in words which is left justified and would like to fill the remaining spaces in the window with "*". Below is the comands I'm using:

/E 545

/ &SPELL-WORD&&' and 'SPELL-DECIMAL(2)'/100'&

2.) When I use &REGUD-SNETT& the window must be 17 character to show the amount. Is there a way the shorten the window to 15 characters and still have the amount show?

Thanks,
