Ask for a FUNCITON about string?
Could you supply a FUNCTION for me that can fill character string with space in its back for the reason that the character string is not inadequate.For example,I define a string named 'PO' of 30 bits length and in fact 'PO' only 10 bits length,so need to fill space of 20 bits in its back. At one time ,i try to use CONCATENATE ,but failed.
If you know ,pls don't hesitate to tell me. I will award you .
